I help moderate a Discord community which caters to fairly similar interests as this site has done for so long. Recently an issue of legality was brought up to the staff, since the server was public and alllowed anyone who joined to see the channels full of inflation art, weight gain art, etc. Now, the important thing to note is that if you wanted to see fetish art that contained explicit content such as nudity or "excretions" of any kind, you had to confirm you were over 18 to access those channels. But what has been brought into question is the legality of knowingly allowing minors to see ANY kind of inflation art, SFW or otherwise.
I figure, this site has been around for a long-ass time and has no real age gate. You must have encountered something in the site's time alive, how was it dealt with, and what is this community's policy on minors?
I could be wrong, but I'm pretty sure that when you created your profile, there was term agreement. That releases people like Luther from liability at point from being sued for underage people visiting this site. Pretty standard stuff.
