The major culprit was using cctip service from time to time (I used to use it quite often, but recently had not time, so I'm not 100% sure).
The other reason might be engagement in #TwitterCensorship and freedom of speech posts. It might have threatened Twitter's view as a place of exchange of information and opinions.
Posting hive links shouldn't be the reason behind suspension, because lots of people do it and it didn't give enough reaches for Twitter to bother.
