Agreed.
I’ve seen quite a number of users return after a week, a month, six weeks, whatever and fill out their profile (usually Spammy) and still they haven’t read a post, far less made one. We even have members imported from vBulletin, with 0 posts there, who have popped up on Discourse at some stage, filled out their profile, and not read a single post.
Really? Do they not have even the slightest curiosity about how the new forum looks compared to the old? Apparently, they have no interest in the forum at all, beyond using it to promote their fiverr account.
I actually feel these accounts are worse than those who sign up, complete their profiles - and never return. Some of those, at least, may have had good intentions, but returning simply to Spam your profile whilst ignoring the actual forum is just cynical, IMHO.
