Typically I don’t, the only reason I pull it up is because I have posts from 10 years ago that still get responses every month (I get e-mail alerts for those posts). Usually I’ll just message the user with information and an alternative forum I’ve setup in the past if they need more answers (it’s really niche and this forum format (reddit/lemmy) really doesn’t suit the topic). I keep thinking one day it will be all bots just leaving messages but they respond and usually sign up on the other site. So, I feel conflicted about deleting my posts or not responding because it is actually effective at connecting to new people, at least for the time being.
