Are they owned by the same company?  I used to think that if a POT posted on both sites, it meant that they were serious.  But it seems like the double posters are all fake.

SA is owned by Brandon Wade. He also owns WYP and I think he owns one other "dating" site targeting uber-rich men.  

 
It's not uncommon to see an SB post profiles across multiple sites, just like you may see the same woman on Tinder and Bumble.  

 
As long as the profiles have the same key data (age, location, height, even text), I don't see this as a red or yellow flag. It's just a POT casting a wide net in the hopes of engaging more POT SD's.  But if you see the same pics with diff info, that's probably a scammer.
