Until I implement a better system to screen out spammers, I will be closing registrations on Fedia.io. That’s not what I want - I’d like for it to be available for legitimate accounts, but the spam is off the hook.
Anyone seeing this can send me an email ([email protected]) and I’ll get an account created for you in the mean time.
You don’t search for hashtags on a content aggregator like this (Lemmy itself didn’t even support hashtags until very recently), but for communities / magazines that fit your needs that you subscribe to for a more personalized feed (I’d use external search tools to find communities though, as mbin’s magazine search can only find what’s already federated) - or just browse /all and let whatever is federated hit you.
