Again, this might be an UI/UX issue, but there is no misreporting.
What you are seeing is the homepage of selfhosted.forum, which is an instance that by itself does not take any users and is only the home of the communities, like !homelab or !main.
Alien.top works by being a home to accounts only (no communities) and they follow specific rules about what “which content from each subreddit should go to which lemmy community”. For example, content from /r/homelab will be posted by alien.top to !homelab.
The “about page” of selfhosted.forum contains information disclosing that the instance is part of the “Communick News Network” and promotes two alternatives for the people that want to sign up for Lemmy. Granted, it is missing information about the selfhosted instance is supposed to be about (which I have done already in other instances like level-up.zone) , but this in any way means that the “instance” is misreporting itself.
alien.top is a new level of Reddit crossposting spam
Whoever is in charge of that instance, STOP....
