The site is weird. It's an industry networking site but the only people in the industry on the site are the paid guests the site pulls in to schill their knowledge or input on your script. They aren't actual members and don't contribute anything for free. You can't network with them. The actual site members are mostly newcomers breaking in.
It's truly a great business model. An endless amount of desperate hungry writers and a matching supply of struggling disingenuous "execs" waiting to take advantage of them. Brilliant idea. No surprise why many of them stay anonymous now.
Paying to pitch is a waste. You'll find it's a total dead end toward development and it should just be illegal. Most execs selling their time to hear pitches couldn't accept any I. P. or submit anything to the companies they work for even if they wanted to. One told me flat out they only take scripts from the top 5. Yeah? So, uhm, what are you doing listening to my pitch?
In the same way that paying an agent to find you work is against the law. Paying to pitch should be as well. Only a matter of time till someone ensures that's the case and this ridiculous circus act is brought to a close.
