Historically I have always been very much on the side of requiring truly solid evidence before even suspecting a person in disguise. I have always been pushed myself hard to avoiding making what seemed like obvious connections as, in most every case I've seen, these 'obvious connections' tend to only make sense in the context of a game with 50 players and not in the context of a city of 70 million.
However, given recent changes to the disguise system and the introduction of the appear system, I think that we really need to reevaluate. I think even staff needs to have a talk among themselves on this issue as it seems to me that they don't share a common understanding of what the end goal is, what the current state is and how to enforce all of this. I don't mean this disparagingly. There have been a lot of recent changes in this area and it's natural for it to take time before people become comfortable with it all.
When I read Slither's posts in relation to our two most recent disguise updates I get the impression that his development efforts are intended to flip our current approach to disguises and meta. It's to make it so that a person in disguise no longer has the right to xhelp and say to staff, "Bob was totally meta when they IDed me!" Because the answer will always be, "You have the tools needed to avoid this. Use them. If you got caught then you got caught. That's on you."
That is completely contrary to our current state. Where people in disguises are constantly xhelping with complaints of meta and expecting staff to sort it out. Where the burden of proof was on the hunter. I get why that was our stance for so long as, given the tools available to people wanting to use disguises, it was far too easy to ID people in was that did not make sense given the massive population.
What I don't think is tenable is both giving people the super powerful tools they have today with enhanced disguises and appear AND still maintaining the up to now standard regarding what is allowed when it comes to IDing people. Together it puts gives those using disguises and appear WAY too much of an advantage.
If we want disguises and appearance tools to be as powerful as we have made them then we need to back off on the "prove you have watertight reason to suspect" bit. If we want people to have to provide watertight reasoning to suspect then we need to really limit the power of disguises and appear and, ideally, provide more IC means for people to combat disguises using things like forensics.
