i'm....not getting any popups at all tbh?? i checked mobile and both firefox and chrome on pc with adblock off but idk maybe it's my firewall?
you can always contact the staff through email, tumblr, twitter, and facebook
the one that seems to be most active is tumblr
here's a page on the site that has all the links and a bit of a "how to" if you want to send an email
/////EDIT: aaaaaa okay so i just checked from an incognito browser, where i wasn't logged in, and got a popup. the popups don't seem to occur if you have a subscription, but they do if you're logged out or have a regular/free account : ///
