Can you point to some examples? Note that they have to be examples which only apply to one side (I'm going to assume you mean conservatives) and aren't standard violations of ToS.

If by "suppressed" you mean "suspended for repeated violations of ToS even though they'd protected him for months by saying he was POTUS and therefore newsworthy and should be granted much more leeway than other accounts", sure.
