Yeah that pretty much lines up with my expectations - I've seen the type of behavior described both in real life and in various online spaces. Luckily never ticking all of the boxes at once, but they don't need to to cause a lot of needless suffering to themselves and collateral damage to the people around them.

The worst situations usually were if someone with this kind of self-sabotaging coping mechanism for some kind of trauma (because that's what it usually seems to be in my experience) ended up in some kind of moderator position in some on-line community, which they tended to seek out to get more control to cope with their fears.
