Then I turn around and sue Fiverr. Didnt you guys explain the rules to this lad? Yes we did, Gavel I vote in favor of FD....

lol, anything can happen, theoretocally, BIAB could say, hey that guy is using our bass line on that hit song, we want payment...

EZ piano could say, hey that guy used one of our intros for his hit song. It could go on an on i suppose.

One thing Id do is make sure the guy trying to sue doesnt work for anybody again. "Whatever you do dont ever hire this Ahole, hes there to look for opportunities to steal your music"

Funny story My dad knew a guy ...who knew a guy who was a singer, and Frank Sinatra was known to have much pull in the music biz, approaches the guy and says "hey, will you do a concert for a charity I like'? No, I can not work for free, i have to be paid...and the legend is Sinatra said "Ok, dont do it, but you wont work for a year" Sure enough, guy doesnt work for a year. Sinatra comes back next year, and says, Will you do the concert this year? Yeah sure, ill do it!

One thing you dont want is to have a bad story told about you. Couldnt be good trying to steal rights to a song you dont own
