twitter account restricted after light automation

I use simple automation for twitter — 5 tweets per day, retweet relevant content, follow 10 people. Is very light, not spam.

Today account get restricted for 'unusual activity'. I do same thing for three month without problem.

Did twitter change detection or I trigger something?

automation is always detectable

Three months of automation. The pattern was detected.

Twitter's detection looks at timing patterns. If you tweet at the same times every day, with similar intervals between actions, that's a fingerprint.

Randomize everything: tweet times, action intervals, even the order of actions. And vary the content length.

I will try randomization. Thanks for advice.
