Shouldn't the #fediverse adopt limits to the amount of #hashtags that can be used per post. I dunno... 10 or so?
I mean, it's fine to have hashtags to aid in discovery, but it can very easily be abused (and is, constantly) by spammers and people who don't know any better.
I don't mind having posts with many hashtags on my timeline, but I do mind to be faced with hastag walls (and little else) on a regular basis.
So... yeah.
And if not the fediverse as a whole, at least #mastodon.
