How is it unsolicited?
Do you even know the meaning of
Unsolicited?
For your information, it means not invited or not asked!
So if the user you quoted used the word unsolicited DMs he is even more right that you're!
Furthermore, since Jet Cash never asked for PMs or create any thread or mention such a thing anywhere that he is willing to sell his account then it's an unsolicited PMs which is even one big red flag and can be worth banning!
The forum has a restriction on how many PMs a newbie account can send and Unsolicited PMs is one of the reasons.
So next time use Google to know the meaning of a word before you respond. period.
