That's not an active campaign signature; he's just wearing it for fun and posting to increase activity points, because I don't see any reason why they'd continue making more than 20 1-2 liner posts every day.
It seems the signature has a referral link. perhaps he is trying to get some referral from the signature. He knows what he wants LOL.
I see two reasons now.
[1.] Referral spamming
[2.] Increasing number of posts.
Its better that he open an interesting thread or a a thread full of good information if he wants to maximize his signature with his referral link on it, I thought he is on Royse777 campaign because its hard to get on Royse777 campaign with this kind of posting behavior.
He has a tag as a
Chatbot text spammer
and he is bringing it on his posts now, its up to moderators to decide on this behavior.
