1) It’s not worth a legal hassle even though you have done nothing wrong in my eyes.
2) If @DJBam does sue you for defamation please call me for a deposition.
3) Countersue @DJBam for defamation if he is dumb enough to sue you for defamation and please call me for a deposition on the counterclaim.
4) f*** you @DJBam !
I do agree he is not worth any legal action. I have read the entire thread from beginning to end and I do not see where you did anything wrong.
The screenshots you asked for, in which he failed to provide so you uploaded yourself, clearly show you did respond to him and offer prayers.
He seems to be butthurt about not being offered back, but was there anything in your communication stating you would bring him back at any time? If it wasn't in a contract, he has nothing against you there except entitlement and hurt feelings.
He seemed very eager on calling you out and trying to get the members of your site to turn against you, and now he wants to talk about defamation and damages to business. Unless there is more to this story this thread does not divulge, he is actually the one who is guilty of defamation by stating you never responded when your screenshots show you clearly did.
It appears on the surface he is wanting someone to blame, besides himself, for a failing music career. Or, maybe he's trying to make a quick buck thinking he can get a quick settlement out of you...money for nothing is usually the #1 reason I see people sue.
With all of that said, I do think he needs to issue a public apology, not just to you, but to all members of the site for the way he acted. If he does that, consider being the bigger person and remove this from Google.
