Blacklisted and spammy proxies

Hey! I am fairly new to the IG stuff, most of my accounts are ~3weeks old. I am using 2-3 accounts per proxy. I got some INSTAGRAM PROXIES from Provider 1, and some PRIVATE proxies from Provider 2. Yesterday I found a proxy checker whoer and it appears that:

All proxies from provider 1 are BLACKLISTER (spam/infected) undetected as proxy.
All proxies from provider 2 not blacklisted, but detected as proxies.

I haven't got many problems yet. I got phone verification maybe 3 times per 3 weeks per 10 accounts. 1 of the accounts using provider 2 was banned. Before that it got 2 phone verifications. I don't really know if I can blame proxy for that, the account had ~150 Followers. ~1300 Following, maybe following 150-200per day, but the content was really bad and overused everywhere.

What do you suggest guys? Should I buy proxies from another provider?

bump. Please show some LOVE! <3

I would like to know it, too Which proxies are working with instagram follow liker?

Ssl private proxies in sales thread. 10 stars service and quality is amazing. Virgin proxies or whatever. It just spins along.
