I guess that could be in regards to user profiling.

Since no fedi platform aggregates user data like “user xy always upvotes topic a, therefore I will show him more on topic a via an algorithm”, or shows algorithmic advertisements, or sells user data for advertisements etc, I don’t think it’s relevant to GDPR at the moment.

Thanks to you too! I see you in a lot of communities lol

Same here. It might be that the overall number of Lemmy users may be shrinking, but some of the communities I’m in are getting to a more sustainable level of activeness compared to automn.
