That isn't enough but someone here advertising selling of account meaning this is encouraging more scammers to scam people here, even if I can recall correctly that the forum doesn't moderate scam but it shouldn't be that vulnerable where any one can be easily scammed and I think something should be done to avert this from occurring or reoccurring.
The forum encourages free speech. And free speech also means that account sales and scams are present.
Since account sales can also lead to scams, both account sellers, buyers and scammers are being (red) tagged when found.
Look at the prices place on forum accounts.. I don't know if this has been happening so far here and will quote for people see and read it.
I think that it's related to both decrease of pay in signature campaigns and increase of chance a sold account may get found and tagged (making it useless for most signature campaigns).
My question is what is the best ways to put this to an end. Because from his profile I sees lot of tags.
This was asked / discussed before, in a way or another. You cannot. Even more, it's better not add a restriction against free speech on this matter, since account sellers will just advertise their "business" elsewhere (where there are even less chances to find and tag them).
