How many proxies do you usually use with Scrapebox?

Just wondering.
I'm usually anywhere between 10 and 60.

What about you guys?
Do you use the Google check too?

I usually use between 10 and 40. I use public proxies. I use the old proxy checker, which everyone seems to agree is the better one to use. I run a proxy test about three times to finalize a proxy list. It produces better results that just one or two proxy test runs.

Most people who sell scrapebox lists will tell you that anything more than 10 proxies is sufficient to get a high success rate.

750 right now.
usually between 600 and 1000 approx.

That may be more than needed but it lasts longer so I don't have to harvest everyday.

I use between 30-35 private proxies which seems to be working well.

10 private proxies is more than enough
