OK. I was using an add-on for SB I recently bought the license for.
And...my IP was getting shut off.
I finally remembered today that SB doesn't work with some kind of proxies...checked and it's CONNECT.
So, is there anything else I need to know when checking?
Maybe a feature request?
Have multiple assignable proxy sets in GSA Proxy Scraper so different ports can use different proxies among the total working list?
So one port can be all GOOGLE-passed for SER scraping, or just anon for SER posting, and another port could be all GOOGLE-passed (minus CONNECT) for SB? Etc...
Also, using GSA software, my IP hasn't been shut again...except when I turned up the threads on PS to check working proxies. I'm going to wait a bit before doing that manually (before a SER run) again...
