Well the point is that the person who had access to my account has contacted a bunch of people, and I'm worried about them having had moved the conversation to other mediums (e.g. email, IM) and they believe they're speaking to me, but speaking to a scammer. However if they see my account has neg rep, they'll likely read it
Did you PM the individuals that were messaged? If so, they'll probably see that before they check your profile. The only issue is that if anyone is still having a conversation in another medium, then they will most likely go forward with the transaction(s) without checking your profile. Though I could be wrong.
