I have just realised that alien.top seems to be mirroring reddit accounts, posts and comments, without labelling them as such. What is the point of this one way mirroring? As soon as users realise, they are going to just leave. There is no point having a discussion with a bot that cannot respond.
The legal right to correct or remove PII is also part of the GDPR and its implementations by the states that implemented it. This isn’t a blanket “I can take down everything with my name on it” law, but it’s also not something that just applies to search engines.
I can see why Facebook didn’t enter the EU with their Fediverse thing, operating a Fediverse server as a company under the GDPR seems like a legal minefield.
