I swear, I bet these "Newgrounds Death" things inviting me to join the server are most likely those bots, but I don't really know if they're actually bots or not. Like no, I don't wanna join that server, I have things to worry about.
That's why I delete these comments and block these bots. You're likely not the only one so I'm also on the same boat.

You are not alone, I got four messages from these accounts, there's even a forum thread about it: https://www.newgrounds.com/bbs/topic/1549143
Because I don't trust at all these links and I don't want any of my fans and random people visiting my news blogs to click the links even out of curiosity, I set all my comments as approved-only so only the spammer and I can see the link and once I see it, block, report and delete.
