Casanova's been beefing with Tekashi 6ix9ine lately. He also apparently has NYC problems with DJ Akademiks, who he recently threatened. 

At the bottom of Nova's message, he brought up Akademiks facing an illegal gun charge.

"Better stay on the side alk Mr and keep my name out your mouth and pray beat that case cause lord knows I run them jails cells," Casanova writes.

As far as their beef, it's not clear what AK said to anger the Brooklyn rapper. But it could be that he keeps putting his posts on his IG page.

Do you think Ak is worried about Nova, or is he used to being threatened?
