In local community FB posts I'm seeing replies from people with usernames like DaringAlligator2732 and ConcernedHomeowner14048. These don't seem like the "real identity" facebook usernames; they kind of feel like anonymous or sometimes even randomly generated names. How and why does that happen? Has it been happening for a long time?
looks like the exact same system that Reddit used for their trashy usernames too
wouldn't be surprised if it's all the same database
Same agency.
