As Bambu said, he is not breaking our rules, but most of our staff members try to act based on the spirit/intentions of our rules, rather than continuously going as far in their enforcement as is technically permitted, so that is definitely something for Deagonx to try to take into careful serious consideration before engaging in such behaviour in the future.
The whole thing with comment deletion is a bit off-topic to the primary incident, but I'll speak on it briefly here because it has come up a lot, and I've mostly avoided saying much on it because it is not the focal point of the discussions where it has been brought up, such as this one.
As Bambu said, my intention is to follow the letter of the rule when I delete comments, it isn't personal. Just as I deleted Gin's comment providing his proposal, I deleted an earlier comment which chastised Arcker's actions even though (obviously) I agreed with it. When it comes to RVRT the flow chart for what comments are allowed is fairly simple, so a lot of comments end up getting deleted. When I became a mod, unhelpful RVR comments was somewhat of a focus for me, because I'd seen a lot of RVR debacles get entirely out of hand largely due to unhelpful interjections from people who had no business being here other than the fact that they wanted to participate in the ongoing drama, which just made already messy situations even messier. This is an issue because the RVR is often the primary avenue to get staff assistance in dealing with a user who is being persistently rude to them, such as the situation above.
Similarly, in many CRTs that involve controversial verses (or are made by controversial users) it's common to see just as many off-topic/low-effort jokes as actual responses to the discussion. In a recent Boros CRT I literally deleted half of the existing comments, because at the time of me reading the thread half of the comments were just people shitposting. This is also an issue, because the longer a CRT goes on and the more cluttered it gets, the harder it becomes to persuade staff to come and evaluate it and help it reach a satisfactory conclusion, which can be really frustrating for a well-meaning OP who is just trying to get well-reasoned changes made.
These are both issues I felt frustrated with when I was a user, so they are issues I've tried to help with as a member of staff. That isn't to say I've never had errors in judgment, I'm a human being and relative to a lot of the staff I am fairly new to this. However, it isn't something I do out of personal whimsy, it is always out of a sincere belief that a comment has broken a rule.
I have taken the feedback on it seriously and have applied more discretion, which may not be obvious because the absence of action rarely looks like action, but it is something I genuinely have taken into consideration, and I've regularly pursued input from admins in situations where the line is unclear, and I intend to make an effort to be more communicative as Agnaa has suggested about why comments are being deleted.
