I prefer allowing hashtags over site-wide search. People can use hashtags specifically when they want their post to be associated with a specific search, rather than letting people search for specific words and phrases.
Site-wide search works way better for communities structured the way Reddit or Lemmy are structured, since people can easily run afoul of different moderation policies, and get themselves banned from communities for bad faith interactions. You have no such protections on a microblogging service.
If you think that by “toxicity” I am referring to moderators protecting their communities, you are sorely mistaken. That’s a feature, not a bug.
Good, you showed up in a trans-inclusive space and used right-wing jargon (coined by Boris fucking Johnson) that dismisses their testimony on their own lived experiences as being “shocking” and a “distraction”, when they know full well that their rights and their lives are on the line. Sorry you didn’t get a chance to correct the record on the fact that you were ignorant on the severity of the issue, but if you’re still publicly complaining about being banned on other uninvolved instances, I’d say that they made the right move.
