So this happens like a minute after I create the account (with automation), PV it and logout.
What are some things to keep in mind when automating the account creation to not get this? (I use Russian numbers)
Most probably Twitter doesn’t like the IP you’re using during the account creation. Did you use a proxy when you created the account?
Yes, I did use a proxy. But guessing it’s because I didn’t rotate proxies for each account? hehe
If you created multiple accounts from the same IP/proxy and if maybe that IP was misused for this purpose in the past, then this is not strange 
yes, that might the issue, you need to try with another IP and see how it goes, how many accounts do you create using one proxy?
