Scraping and proxies

Hi, Need some clarifications about Scrapebox and proxies.
I got some proxies from this forum and checked via SB and filtered google proxies. Then i started scraping the urls i needed and well almost 95% proxies got 302 error ip blocked?
My KWs are like inurl:sitedotcom keywords

Q. How do you guys scrape? which proxies do you use?
Suggestions much appreciated!

Your proxies will be burned fast if you use "Inurl" Operator.
Guys who do it have more then 1000 public proxies at a time.

Thinking of doing it manually cz i only use it with inurl, site:, intitle etc...

The 302 error or IP Blocked error is due to too many queries from that IP within a specified time frame. The block usually stays in place for about 15 minutes or so (depending on useage).

Only happens occasionally with my users, but when it does it's because I have at least 2 users hammering Google to scrape results. Never seen the issue with Exclusive proxies though.

Really??
I have a dynamic IP and i often use my own IP for scraping and dies after ONLY one keyword scrape. As i mentioned above that my kws contain inurl, and intitle etc and using these get proxies ban in a hurry.
If your exclusive proxies never give error i am interested in trying them.
