My community is approaching about 5k users, but we have a growing number of dead accounts. Accounts that haven't been logged into or used in up to 4 years.
I'm always tempted to delete or remove these accounts, but I can never decide for sure. We've had members pop back up after years of inactivity and I've always seen having to re-register as a barrier to re-entry; a potential stumbling block to getting involved again. At the same time though, seeing profiles that obviously haven't been used in a long time isn't great for morale.
What do you all think?
