Proxies for child accounts

I'm experiencing problems in last days with Storm Proxies using for IG child accounts. Few days ago I got banned more than 70 accounts that were using their proxies in one night. About 20 days before they were working good. Acounts were also for another niches and main accounts, about 10 acc per one main in different niche.

So I'm looking for some quality tested proxies from someone to not lose time testing different proxies.

Thanks!
