As someone who has been moderating a chan with tripcodes (and using them, and not using them elsewhere) for nearly a decade, here is my 2 cents:
Not having tripcodes is not going to solve any issue of attwhoring/unhinged posters, drama, e-celebs, etc... they find a way to do their thing. That is not a good reason to not have them at all.
But, that being said, it still matters choosing to have them or not, because they create very different types of communities.
Sure, the users can choose not to use them, as they did on 4chan, but once a group that do uses them settles, it is a tripcode chan and it will forever be one. Anons exist, but they are secondary, and if you don't know all the tripfriends, you are not part of the community. The way you interact with them "wrong", proves you are an outsider.
And an extra-factor is that small chans tend to attract tripcode users because they are unwelcome on the bigger ones, so it is much less of a choice of the userbase of what mewch should be, and more of a choice of going back to the big anon ones or not. Small anon ones need to be enforced to exist.
So, TLDR, no way around it but to think what kind of community milk wants, and stick to it.
