Twitter bot security

Hi,
I'm a developper and I make a bot to post or follow on Twitter. I have multiple private proxies and accounts made in 2011.
Each account have a private proxy assigned. The account login, post and logout in 1-2s, and every 83 minutes he do this another time. Accounts are not phone verified.

Do you think twitter will ask phone verification or ban account ?

I know this question has been asked a lot of time but maybe there is new security ?

Sorry for my english I'm french.

Thank you

I honestly believe you'll be fine since it's only a couple of accounts you're using

There is 1000 accounts in total
