I have no idea tbh I never really did any of those things. If you just want to create a good account with decent combat stats it's import to just stop botting at some point and don't overdo it. Not sure if botting to max combat is doable.
I seem to recall that I created that myself so it's not an existing font.
Could use something like this: http://www.dafont.com/sf-square-head.font?text=OSBOT it's very similar.
