Basically, I think there should be more strictness within block glitching. It's only ever used to abuse, so shouldn't that be under "Glitch Abuse"? After all, you are glitching and you are abusing. Suggestion is basically to change the rules to make this worthy of a ban.
Just need a more serious offence put in place, or as my previous suggestion. Adding in barrier blocks to these locations stopping people from being able to do it.
