I haven't run across any suspended accounts, although I have seen a few tweets in feeds become unavailable to like--I forget what they called it.

Don't swear, don't use killing in any form... Hmm...the only problem I could see are hashtags where you tweet part of your book. I think all my books have violent moments, and those often make the best tweets because they're short. I haven't been doing those for a while now, and besides, surely Twitter understands that these hashtags were meant for fiction writers. Still, that might be something to avoid in the future.

Thanks for the heads-up, winks.
