Increased Captcha's

Has anyone else noticed an increase in Captchas lately? I can't find a reason why it happens, maybe it's not just bots but all (active) Twitter users that have increased captcha's.
Maybe a strategy from Twitter to slow Bots down. I don't have a lot of bans lately, just an increase in Captcha's.
So anyone else notice it?

Early September Twitter has ramped up on Arkose challenges. After you solve it, wait a day or two and then continue with actions. I got two in a row but now I haven't gotten one in 3+ days.

What triggers these Captchas the most is Following, Unfollowing, Liking and sending Tweets at higher rates. An IP change could also trigger it. They're definitely trying to kill Bot accounts by triggering Captchas more frequently. It happens to normal accounts too, type in Twitter search "Arkose" and you'll see.

Twitter is trying all possible means to disable Bot activities and also protect their new features.
