Here are things I've found useful for posting:
1) Quantity over quality-I have standards. I don't spam threads. I check the traps! I check for promo site updates. I check for public facing pay site updates. That's not a duh ob-V post. Some don't want to have porn on their Twitter or be on dozens of porn sites' mailing lists. This is especially true if you know a site that doesn't (or can't) promote widely. I check DukeSkywalker.com (Kink warning: gagging, cock choking, spit, snot, vomit, golden shower/watersports) and affiliate sties. They will often have first time/rare anal of pro-am and mainstream stars. (If you don't know Luna Mills, you should!) I post to their respective threads with the same above kink warning.
If the promo gallery has identical content to a previously posted link, I will not post it even though it's not technically a duplicate. Quality but with standards. That's not a board rule, that's just my choice. If a promo site has a longer video clip or even one photo that's different, I will post it with reply quote to the first post. Once again, not a board rule, just my standards.
2) You don't need to link content! The mods encourage discussion on babes and their work. I don't like it but others do. Discuss weight loss/gain, breast implants/reduction, plastic surgery, botox (ick), tattoos, piercings, hair styles, contact lenses-anything! Pissed off that Gabbie Carter did a blackface scene at Zishy? Boycotting Blake Blossom because she tweeted that age play causes criminal activity? Think Alexis Adams is waaaaaaaay overdue for a BG anal scene? Post about it!
3) Threads and replies don't need to be about porn or even anything adult. Want to rail Rachel Maddow while Susan watches? Want to start a thread called, "No disrespect to NZ but Boba Fett is not a damn Kiwi!!!" Do it!
