How to prevent locking Twitter account?

Hello,
I have about 80 Twitter accounts, I used them normally for a long time but nearly Twitter often locked them and forced me to verify phone number. Even I add phone number to those accounts, after a month Twitter keeps locking them and require code from phone. How to avoid it?
For more information, I just use those accounts for boosting like to my main account. I switch between account and like by hand. With my clone accounts, I also tried:
- Like and RT other tweet from other people
- Comment and post tweet
- Don't switch accounts too fast.
But they are still locked. I don't use any extension.
I logged all accounts in Twitter app mobile on my phone, is this the reason causing locking issue?
So, is there any solution to safety use multi-accounts?

Yes, that can be an issue. Do you use proxies or change your ip address when switching accounts?

No, I also think it's the problem. But my main account isn't banned despite it is logged with the same device with clone account.
And why Twitter allow logging unlimited accouts on mobile app while still ban if people use it?

It's not a ban, it's just a lock, what you can remove. Your main account is not locked, because it has more trust, probably older and i guess you do different type and/or number of actions with it than with your other accounts.

As to why they allow it, ask Dorsey.

They disclosed the number of accounts, which can be linked to the same phone number. This number is/was 10, probably it's less by now. I'd say, that's already pushing it on the same device, 80 accounts is just too much.

I only added 2 accounts per phone number. So there is no way to safety use multi-account on one device without a software?

That wasn't my point. The point is that one device usually has one phone number. So if they limit you at 10 accs/number, it means that they don't want you to use more than 10 accounts per phone number aka per device.

What clone App do you use? Or what do you use to manage them

I just use normal Twitter mobile app. I just tap on "add an existing account" and it allowed me to log in all 80 account on this app.
Now I have another problem: some of phone numbers I added had been blocked due to long time no use. I can't unlock twitter by code sent in sms. Is there another way?
