That's pretty much how it works in modding. Someone realizes we can do a cool thing. 0.2147483647 nanoseconds later, some starfish abuses it and then no one gets to use it ever again.
Dang, I actually wanted to use this for my server for an actual purpose.
Would it be possible to add a hovering name to a Bot?
no
I don't really understand the point of blocking it. If somebody sees "Badspot", they can just press F2 and see if it's real.
You can fake a user in the F2 list too.
Badspot should block that then, not this. This can actually be useful.
