As far as I am aware, Badges are intended to be similar to reddit's post flair system? They don't seem to do anything at the moment though.
Community moderators can set up badges but even with those in place you can't see them when making a post.
There are devices like Samsung's Xcover products that have the back cover snap into place in a way that creates a water-proof seal around the battery and components inside. It's incredibly tight and has a rubber ring.
If there is something that I can complement Reddit for, it's that the frontpage shows one or two hot posts from each of the subreddits you are subscribed to, instead of showing several from those that are more active than the quieter ones like what kbin does now.
Hopefully several instance owners collaborate on a shared blocklist that will help combat this kind of spam and implement that back into their instances.
Lemmy at least does have a slur filter in place to block certain words that could be expanded to block spam like this. I don't know if kbin has something like that or not.
