Bumping ann threads, ethical or not? ban or not?

Woke up to find someone looking to pump their ann thread (https://bitcointalk.org/index.php?topic=2473151.msg25337405#msg25337405) and some people looking to be hired.

I can do this! PM me, or we can talk via Telegram or Skype

Messaged you

Do you think these users deserve negative trust?

Also someone else started their service for bumping anns

Seems a bit dodgy aye?
