This was my experience as well. Not a single real inquiry, just spam. I asked the mods to delete my posts on those threads and the spam email vanished
hiring posts can be edited without timelimit. also i would put the email in the profile, then you can removed it from there any time easily. i also 'obscure the address as name at domain. never got spam despite posting many times.
But you were awash in “hrony MILFs,” Vi@gra, and mortg@ges, right?
