Problem Twitter shadow ban

i have been managing bulk twitter accounts with my twitterdub software for 3 months now and up till today, none of these accounts are coming live.
do you think the software is the problem?
i've done lots of actions in the past months including liking, retweeting, comments but these accounts is still not out of shadow ban, these accounts are manually created myself, i bought some of them too.

yeah, twitter increased their security and now api bots are quite bad

Twitter is so aggressive with any action on accounts,seems a shadow ban and check if your isn't leaking out any pattern.

Try to simply introduce uniqueness into each account

are you making your action appear natural ?
