'[platform] is censoring muh posts!' is usually a good indicator of unreliability in internet discourse. Perhaps other users are just flagging his tweets - marketplace of ideas and all that.

I too have a small number of twitter followers and so my tweets normally fall far down the stack within a minute or two of being posted, despite my anti-Trump stance and rapier wit. Ermahgerd I'm being censored, this is serious bidness u guise.
