1- a scammer starts a locked thread selling gift cards.
2- uses a sockpuppet to comment saying he sells the same gift cards maybe at cheaper rate and posts his email/telegram contact.
3- another sockpuppet to vouch for the previous sockpuppet.
4- another sockpuppet to confirm the scam warning about OP and vouch for the first sockpuppet.
I see. I hadn't thought of that.
The warning would help a little because newbies would at least know scammers are not banned (unlike most other forums) but a warning next to every post made by a scammer would be much better.
theymos, any chance you make this change?
