In the marketplace section there are a lot of newbies who are bumping their threads more than once in 24h time period.
I am reporting them every day, but it seems like it does not affect them in any way.
Even if they get banned they will just create new account and start all over again.

example: https://bitcointalk.org/index.php?topic=5344034.0
https://loyce.club/archive/members/332/3324652.html
There are a lot of more guys like this.

Isnt there any other method to prevent them doing so?
Is there any other section which have same problem?
