He is 100% that petty. He literally mass blocks people who have simply liked or followed anyone he disagrees with, no interaction. Not an exaggeration at all.
If you read his post above, he stated that he was being threatened and doxxed. I'm sure he was dragged down by a lot of negativity on Twitter so mass blocking seemed like a decent strategy.
I don't have a problem with him blocking people on Twitter at all. I actually sympathize with him. Twitter is a troll fest and he exposed his real self by getting involved in local politics. You know how "passionate" people can get when it comes to politics.
My problem with Garry isn't with his "pettiness" or Twitter blocking. It's solely with his crypto shilling.
