B.o.B took to Twitter this weekend to air his frustrations with Atlantic Records.

“There’s a ban on BoB,” the Atlanta rapper writes in a series of posts. “They boycott me, they are afraid I’ll get too much exposure. When ppl say I’m “under-rated” or ‘slept-on’ … it’s not entirely the case… ‘suppressed’ is a better word. All my social media outlets are heavily monitored and my reach is crippled.”

He then thanks TIP for his support. The rapper formerly known as T.I. signed B.o.B to his Grand Hustle label at the beginning of his career.

“Thank God @Tip got my back and he still in my corner, #HustleGang #NoGenre,” he writes. “To every fan who has ever gave me a RT, a follow, or a like… thank you for spreading the word. You’ve done more promo than the label.”

Even though he doesn’t name Atlantic, B.o.B released his debut album, B.o.B Presents: The Adventures of Bobby Ray through Grand Hustle in 2010, which was an Atlantic imprint. Grand Hustle signed to Columbia in 2013, but B.o.B stayed with Atlantic and released his next three albums with the label, including this year’s Psycadelik Thoughtz.

Waka Flocka Flame has also blasted Atlantic Records this year, saying the label is withholding Flockaveli 2.
