The suspiciously similar account https://suppo.fi/u/Albin7326 is operating simultaneously with the same behaviour: posting in remote instances, and then deleting their posts and comments.
For example, both of these posts were made 2 days ago, and then quickly deleted by the poster:
- https://slrpnk.net/post/3099065 - from the comments, it looks like an advertisement for a suspicious and possibly trojan'd android app disguised as an askLemmy question from Albin9325
- https://slrpnk.net/post/3074818 - from the comments, it looks like an advertisement for a VPN disguised as news from Albin7326
Thanks for investigating this, I'll refer other mods to this thread for discussion as well.
