How to delete tweets from the past few months?

I have been struggling with a bad ghost ban for the past few months. I keep not tweeting for a week and it goes back to normal but no matter how little i tweet it keeps ghost banning me over and over again and i heard deleting ur tweets works...only problem is i tweet a lot and through the past few months there is more than a thousand tweets/rts/replies that could potentially be screwing me over. is there a site or a safe way to delete tweets dating to around past three to four months?
