The Helpers aren't doing their job wrong, in fact, they're doing it right. The
rules are simply enforced, and the according punishment is given for violating such rule, of course some staff would rather not immediately punish, but rather tell the rule-breaker not to do it again, instead of writing a warning up as a punishment. It all comes down to the discretion of the staff members themselves, an example of abusing would be muting someone for Filter Bypass is they haven't received a warning yet from the staff member, as the rules clearly say that first it's a warning, then followed by a one hour mute. If someone didn't give that warning in the first place, then it would classify as abuse. And the staff not giving you a warning straight away is simply them cutting you a break, and giving you another chance before it's a warning. Not all staff have this approach, and giving a warning straight away would not be abuse, because the rules clearly say that the first offense vouches for a warning. Now, some staff may warn straight away as per to their discretion, since the punishment is up to them, however giving an incorrect/severe punishment for a minor would be abuse.
Think of it as in real life, the police wouldn't arrest you straight away for littering, since it's a minor and nothing near a felony. They may however write you a ticket, but that's up to them (the same applies in bypassing filter, they could either tell you to stop, or warn you). Arresting you for committing a minor is simply abuse of authority (muting you for bypassing the filter once is obviously abuse), since the crime does not require such procedure. However littering again, simply tells the police that you haven't learnt your lesson, to not do it again. If they wrote you a ticket before, you may have an even more expensive ticket, or community service. But if they didn't write you a ticket, you would get one now. The severity of the littering and the punishment for doing so, is all up to the officers discretion. The job of a police officer is to enforce the law, if you haven't learnt your lesson the first time, the police will take more drastic measures the second time.
I hope this makes sense, it's all up to the staff if they want to cut you a break or not. And they most likely won't if you break a rule severely. For example, simply bypassing the filter by saying something inappropriate, such as cussing may simply result in the staff telling you to stop. However, bypassing the filter by saying racist slurs, or discriminating others, may vouch you for an instant warning without a second chance.
