Put together, the evidence clearly speaks in her disfavour. While I think that it is legitimate to compare the Western far right to Islamic extremist (which is pretty much the Mideastern far right), her implied allegations of others being nazi, and her condoning of unprovoked violence (as in, not being attacked first) against far-rightists, are clearly over the line and should have been acted upon earlier. Why it wasn't is beyond me, though I reckon that the matter was unceremoniously closed down after Spaces departed. That was wrong, as Spaces was evidently not the only offender. Sepia's offences effectively constitute libel and sedition under Swedish law, and I'd hazard to guess that also holds true for German and British law. That in itself, deserves a warning on its own right.
The fact that she refuses to acknowledge opposing points is problematic in and of itself. However, since Rik's discussion with her happened off-server, and despite her acting like a dick in it, it's not severe enough for us to really do anything about it except take it as a warning sign.
I myself demanded that sepia stop with that behaviour at the last instance, as it had become obvious that it was long overdue. There were no logs of warnings to her before, but I feel that that may indeed be in order soon. I logged mine action in the staff_log on the Discord server for those of you who are interested.
While her slashfic gushing of CotBG-Sarkic characters can be annoying, I don't see that as enough to merit disciplinary action. Usually, she has done that when Sarkicism or CotBG has been discussed. As she posts no pics when doing that, thus not annoyingly taking up screen space, I would not regard the odd comment from her as shitposting. When it comes to cuttlefish, I really do not mind, on the contrary, I think it has a calming effect (cute animals always do), and there is definitely no need for disciplinary action on those grounds. Consider also that, lately, she has been posting far fewer cuttlefish pics, and has generally been far less active on the server, if you find the gushing and cuttlefish that annoying.
