Another proxy thread

Hey guys, looking for some experienced people to give me some advice on proxies. For the previous month, I was using proxymillion proxy and I should they are pretty good however for the last few days I see a lot of my accounts going phone verification super fast, and I am not sure if it is proxymillion proxies or something wrong with setting up accounts on my side. Anyways, do you guys have any feedback on proxies? Which are best for BULK Instagram accounts? Proxymillion seems really affordable, but I am willing to pay bigger price for better quality obviously.

Thanks in advance!
