You know, lemmy world has the largest population, so it’s really obvious when things are getting blocked. I finally did a search today on their side. Only one or 2 per day are coming through. I suspected that they regulated their content, but why not just block me? So weird.
Edit: Someone asked for evidence
Have you checked to see if this behavior is present on other instances besides LW?
It may be that you’re running afoul of an anti-spam filter, most servers have implemented something to rate limit new posts in an effort to prevent griefing or system errors on other instances from bogging down the system. It might also just be that LW’s search function doesn’t update it’s index very often, and that lemmy search in general is… not great. And it might also just be a federation issue, those are extremely common.
As I said in another post, I’ve had a history with them doing things like this when I was on that instance. I’ll check other instances though.
Edit: It might be a spam filter because another one does the same thing. Interesting.
