There will always be a place for static designers in print, but the resources available to developers to make their sites look "good enough" for them (see the Bootstrap Effect or all of these free asset sites) means you're going to need to get your hands dirty to stay relevant to companies and freelance devs alike if you prefer to design for digital mediums.
About the original question, I don't have enough experience working with designers to answer it :) (though I hope to start working with designers soon :) )
"Hellbanning is a practice used by some online community managers for protecting a community against Internet trolls. The practice involves making a user invisible to all other users. From the hellbanned user's perspective, however, they seem to be participating normally in the community. The purpose of hellbanning is to make it impossible for other users to respond to a particular user by rendering their contributions invisible"
No idea whether the editors can un-hellban someone. I guess the best if the user wishes to keep posting to the community is to make a new account.
