Information on the project

The EUNOMIA project aims to assist social media users in determining the trustworthiness of information on social media platforms. To this end, it provides a toolkit integrated in decentralised social media platforms offering trustworthiness indicators and enabling users to and express their trust on social media posts. Participating in this research you will have the opportunity to experience the EUNOMIA toolkit and provide your feedback to further develop its features. You will need to sign up on EUNOMIA instance of Mastodon federated platform (please see here Mastodon’s privacy policy) and act as you would normally do in your personal social media (i.e, post, comment, share) using also EUNOMIA’s features such as trust/ don’t trust button and other features. Note that there may or may not be, at random times, false information injected into the EUNOMIA instance by different users (that may or may not be controlled by the researchers), in order to evaluate user behaviour and responses.

EUNOMIA unites a highly complementary consortium of 10 partners from 9 European countries from cross-disciplines and cross-sectors including academic, decentralised social media, public journalism organisations and SMEs. Specifically, University of Greenwich, Blasting News, Trilateral Research, SYNYO, INOV, University of West Attica, University of Nicosia, ORF, Eugen Rochko (creator of Mastodon), SIMAVI. The joint data controllership is between EUNOMIA project partners: University of Greenwich, INOV, University of West Attica and University of Nicosia.

What information do we collect?

EUNOMIA instance collects all information collected from Mastodon platform:

Basic account information: If you register on this server, you are asked to enter a username, an e-mail address and a password. You may also enter additional profile information such as a display name and biography, and upload a profile picture and header image. The username, display name, biography, profile picture and header image are always listed publicly.

Posts, following and other public information: The list of people you follow is listed publicly, the same is true for your followers. When you submit a message, the date and time is stored as well as the application you submitted the message from. Messages may contain media attachments, such as pictures and videos. Public and unlisted posts are available publicly. When you feature a post on your profile, that is also publicly available information. Your posts are delivered to your followers, in some cases it means they are delivered to different servers and copies are stored there. When you delete posts, this is likewise delivered to your followers. The action of reblogging or favouriting another post is always public.

Direct and followers-only posts: All posts are stored and processed on the server. Followers-only posts are delivered to your followers and users who are mentioned in them, and direct posts are delivered only to users mentioned in them. In some cases, it means they are delivered to different servers and copies are stored there. We make a good faith effort to limit the access to those posts only to authorized persons, but other servers may fail to do so. Therefore, it's important to review servers your followers belong to. You may toggle an option to approve and reject new followers manually in the settings. Please keep in mind that the operators of the server and any receiving server may view such messages, and that recipients may screenshot, copy or otherwise re-share them. Do not share any dangerous information over Mastodon.

IPs and other metadata: When you log in, we record the IP address you log in from, as well as the name of your browser application. All the logged in sessions are available for your review and revocation in the settings. The latest IP address used is stored for up to 12 months. We also may retain server logs which include the IP address of every request to our server.

Additionally, participants’ trustworthiness votes will be collected to be displayed and analysed to inform further indicators. The trustworthiness scoring results solely on participants’ actions with no interference from the researchers. For the purposes of the study, EUNOMIA researchers will also collect participants’ feedback on the toolkit.

We recognize the importance to protect and secure the participants’ personal data and we are committed to adopt and implement all appropriate technical and organizational measures for the security and protection of the participants’ personal data. It is necessary to process such personal data for carrying out the research in a proper and effective manner. However, participation in the research project is done so on a voluntary basis and based on the participant’s consent.

What do we use your information for?

Any of the information we collect from you may be used to provide the core functionalities of EUNOMIA toolkit and its further development. We rely on your consent as the lawful basis for doing this.

During various phases of the experiment, participants will be contacted by the researchers to collect feedback on the EUNOMIA toolkit, which will be used to improve the ongoing experience and to inform results and evaluation. Note that the email address you provide is necessary so that we may facilitate the setting up of your account to participate in the research. We also use email to provide you with project related information and feedback.

Note, the administrator of this EUNOMIA instance reserves the right to remove a post/ toot and ultimately delete an account, after giving suitable warnings, when there are abusive or inappropriate posts/ toots.

How do we protect your information?

We will pseudonymise and where possible anonymise the data you provide us to the extent possible when and if they will be used, removing all personally identifiable information where appropriate. We will only collect and process data that is strictly necessary for running the research, for our internal processing, administrative purposes, and to enable us to contact you if we require further information.

What is our data retention policy?

The retention policy follows the one of Mastodon making sure your posts and online interaction will not be disrupted at the end of the project. See following from Mastodon’s privacy policy:

We will make a good faith effort to:

  • Retain server logs containing the IP address of all requests to this server, in so far as such logs are kept, no more than 90 days.
  • Retain the IP addresses associated with registered users no more than 12 months.

You can request and download an archive of your content, including your posts, media attachments, profile picture, and header image.

You may irreversibly delete your account at any time. Upon deletion of your account all your posts/ toots will also be deleted from all EUNOMIA nodes.

Data collected strictly for research purposes, such as participants’ feedback, will be pseudonymised and securely stored for up to five years after the end of the project.
