I'd like to add constantly getting into conflicts on Steem. I know people who have a fair bit of stake but whose earnings largely depend on self-votes or various types of artificial arrangements. If you enjoy positive interactions with others on Steem, you're bound to create a following and support organically. If you constantly get into fights, there could be something to fix about your approach.

I would include people with the most tendency to seek out or create drama on Steem on your list. In my experience, it is entirely possible to steer clear of acrimony here. For me, Steem has never been the kind of cesspool some people claim it to be. I've witnessed some of it but I have never looked for it or willingly participated in it.
