Traffic Bot Accounts in Room?

[NotYou]

This is very strange and has never happened in this model's room before, I am hoping it's unrelated to my problem from yesterday, but this is a different model from that but see the image below

"Userpbr" ones all say colombia on the profile.
The "userctnd" ones say Netherlands

That does seem unusual, to have incrementally-numbered grey accounts.
And whenever I've noted the room count significantly higher than average, it's always anon users rather than greys.
Maybe the work of someone sitting there creating these manually, rather than auto-generated by a bot?
