The Mods on most crypto subs were horrible. Any opinion that is contrary to the groupthink would get you immediately disciplined.

And yeah, that happened on other subs too. But the crypto subs were particularly insidious because you knew that some of them were active since the beginning of crypto, which means they got in early, and are likely filthy rich. So they don’t have a day job anymore (other than shilling their latest crypto project), and have more time to be petty and vindictive.
