Same. I've been blocked many times on Medium, usually for disagreeing with someone who has a massive echo chamber of folks agreeing and defending their position. But I do only really read writers I like, I will comment because I respect their position - and I only bring out the snarktillery when absolutely necessary. It's a shame how quickly some people reach for the block button, because it's far too easy in the modern age to label 'dissent' as 'trolling'.
