Switching proxies?

Right now I am running 3 accounts per proxy (75 accounts 25 proxies(, but I'm getting phone verifications even though I'm only following max 80 people per day. So I'm going to switch to 1 account per proxy. Can I keep my original 25 proxies and just get 50 new ones? Or should I get 75 new ones because the 25 proxies may be flagged? Also, will I get any phone verifications If I switch proxies?

Just get new ones.

Let the accounts stay idle for 2-3 days and then warm them up gradually for good measure.

People travel and access IG from different locations. IG won't penalise you if it's not sudden.

switching should be no problem ........ if your proxies are flagged ???? start with new ones i guess thats the better advice.
