Multiple Accounts 2

Today I wanted to check the event board for any new information and saw these three accounts causing trouble 😑 Some of the posts have very similar content, like how they keep talking about the Tainan railway underground project recently. I didn't want to get involved, but what's the deal with them constantly posting in the event section? Can't they post in the free section? Their names are so similar, it's like they're really afraid people won't know they created multiple accounts.
