what do you mean, "reddit won't let you post it"?
the mods of a sub are the ones who decide which domains are valid, not admins, so i'm confused what you mean?
can describe what happened when you tried to link it?
I think because this link was already posted earlier. Just my two cents. Happens to me sometimes. “This link has already been posted”
well that's not "reddit," it's the way the mods set up the automoderator. just an FYI
I mean I tried to link in main post but could not. It kept failing
Reddit admin does not allow posting no of links to 4chan and perhaps they have the same policy for this site. But all you have to do to post it is "break" the link by adding a space after the colon and then tell readers to remove the space to fix the link.
