Simply spammers will continue their spams whether in off-topic or elsewhere.
For example, in the other compagns that don't pay posts in the off topic section, politics... spammers will bombard game & rounds.
In this case another member will suggest to not count the post in this sub.
It is like a circle, i will not say i don't support your idea but the problem is that you may reduce their earnings but will not reduce their spam..

Better to report them to mods...
