Hello, in your case I don’t think it depends on proxies one hundred percents.
You should split your proxies and test.
5 Accounts follow on the A plan
5 Accounts follow on the B plan
Or
5 Accounts follow on the proxies A (Highproxies)
5 Accounts follow on the proxies B (Another Provider)
etc…
You will see what plan matches for you, and you have to suffer from Action Blocks, it is no longer a surprise (I guess)
