I believe this has already happened at least once.
Take these questions with more than a few grains of salt, but keep in mind that the server stance on what qualifies as self-antag and/or powergaming has relaxed considerably since that conversation with the player took place. What was previously seen as problematic may no longer be enforced as such as we have tried to dial back as a team and let players have more creative (and disruptive) freedom.
This by itself is not an issue.
This has the potential to be an issue, but this is an incredibly vague statement that we can’t do anything with. The old rule about “do your job and let others do their job” has been reduced in scope significantly since this player previously found themselves on the wrong side of it:
Without an in-character reason, let other people do their job.
Are they actively disrupting someone else doing their job, or avoiding someone who is both ready and willing to participate in shenanigans? If not, then breaking and entering is probably not against the spirit of this rule and should instead be reported to security.
What exactly was done with said plants?
Again, what was actually done with said plants?
I have seen this player’s botanical habits as an admin matching what is described in this thread fairly recently, and I have gotten involved as an admin with it… on an IC level, such as by sending a fax to security to remind them that crew should not be allowed to keep inherently dangerous items.
I also do this with explorers and a number of other things that were previously considered to be powergaming - send security in to confiscate that shit. Players in rounds witnessing this sort of thing should be doing the same thing rather than telling admins, unless it’s particularly egregious or involves the gathering of items outside the scope of one’s job.
Creating a flamethrower is not feasibly within the scope of someone’s job, but growing plants for a botanist definitely is, even if they’re weaponized plants. It really comes down to how they are being utilized, or just how reckless they are being with them and whether they are making an effort to remain IC about it.
