That's the rub these days, especially with the younger women, especially ones in and around online communities. If there's someone being really creepy and stalkerish, it will get around.My guess is she got a sudden amount of spam with "warnings" about Chris and just decided to block him based on that. She's probably too busy to want to look into his Twitter history.
It doesn't help that Chris does have a genuine history of doing this. His entire trying to shift the blame certainly just adds onto everything.
The difference from say, the Golden Age, is that instead of Chris being the community, he's interjecting himself into other, established, "Normie" type groups of people. Groups that are open and tolerant, and he still manages to make an creepy ass out of himself.
