A version of RPR10 is already in rule 0. I think it's fine keeping RPR10 in the roleplay rules, because the rule 0 variation already covers all the cases we'd want to cover in LRP.
Rule 0 should only be invoked by admins when it is in the best interests of the server.
Admins have intervened before and will do so again in situations where a player, regardless of antag status:
has repeatedly delayed round-end by recalling the shuttle when most other players are dead or want to leave
has habitually used the same strategies to cause mass death or destruction (i.e. bombs, hyper-optimized viruses, etc.) to the detriment of the rest of the server's experience
Rule 1 covers situations where players follow the same strategy in a play-2-win manner and who barely do any roleplay in getting the things they want
Breaking into staffed departments to take resources, or hoarding station supplies with little IC reasoning can be harmful to the experience of other players. Communicate first if you desire something that you do not have access to. Players may defend their workplaces from trespassers who damage or steal property with relaxed escalation.
This is primarily a roleplay game, so it can be justified that you are harming the experience if you are breaking into highly secure places of a round without good reason because your character would have no reason to do that. Generally, if you want to break into somewhere, make sure you have a valid IC reason to do so if you don't want to get bwoinked by the admins for your behaviour. The bar is generally lower on LRP than it would be on MRP because of the lack of roleplay rules, but you can still get bwoinked for it if what you're doing truly has very little justification.
The only reason we don't bwoink more often for it is because:
1. The player may have already been dealt with by the people who staff the department
2. No one ahelps it because no one is around to see it, so they keep getting away with it.
3. If it's not done early enough into a round, they may have a valid justification to their actions which would require asking them about it. I don't usually interrupt people's gameplay if no one has ahelped about their actions.
Like I said, the bar is low, so if you're fetching stuff because of an IC gimmick or construction you are preparing for, that will usually get you a pass OOC even if you don't get a pass IC (you may still be arrested by security and attacked by people you are stealing from). And no, powergaming is not really a valid IC gimmick unless you're the Captain or a secoff, because technically these guys have to deal with antags, so we don't tend to care that much because antags usually powergame just as hard as the secoffs.
