If you buy proxy with rotation every 10 minutes and seller doesn’t give you URL or telegram-bot for changing IP very likely it means your proxy is shared. Other people can work with this proxy at the same time.
When you buy private mobile proxy you will get link to change IP which you can insert to your soft. You can work in one account then change ip and enter next account, change ip after you finish work, enter third account and so on.
Also you can create private mobile proxy using your phone and use link for changing ip. It will be cheaper than buy ready-made proxies.
Since there are fewer mobile IP addresses than there are people who access the Internet, multiple people use the same IP address when accessing whatever sites they’re currently on. That means when an online marketer starts working through mobile Internet, they blend in with the “crowd” and it looks like users’ natural behavior so twitter won’t lower the trust to your accounts. Although, of course, with the same type (and parallel) actions from the same IP, the trust can be lowered.
