OT: I don't recall a situation like that happening this year. Not from a reputable staff member. For some reason, every staff member on MPGH has too much love for the site.
Or they're just too lazy to do that.
Others do however spam the forum, get premium member, exchange thanks and rep to have a good looking profile to get people who know of no better to trust them and make off with their money.
That is undeniable.
You should never trade with a person for bitcoins in my opinion unless you know the person really well. Paypal goods and services is the only way to deal safely.
