hateblock

the action of using the 'hate speech' or 'incitement to hatred' reporting features on content-hosting websites with the goal of removing content from public view.

usually used when one's feelings have been hurt; with internet users becoming more sensitive, is therefore used increasingly on content that isn't really that bad, or on content that is 100% scientific/factual/objective without need for subjective opinion, making the content-hosting websites more tame and less interesting over time. an example of the tragedy of the commons.

"hey - I uploaded that video about the chemistry of A. Witz last night. did you see it yet"
"I was 10 mins in and the page refreshed to 'content restricted - inciting hatred'"
"inciting hatred? odd"
