Even the most closed community will often accept a contribution if you are polite and email them.

An open source developer had disabled pull requests and other operations on their repository because they were fed up with harassment. They gained a reputation for being extremely disagreeable at that time. I was unaware of this and simply assumed that was how the project worked. I had to do some minor investigative work to find their email address and I sent them a polite, low pressure email with my unsolicited patch and made it clear it was fine to use it or ignore it. They thanked me, explained the situation, even apologized for the difficulty, and said locking things down was the only way they knew to cope with the situation, and of course applied the fix.
