Happens at home (Safari and Chrome), at work (Chrome) on both windows laptop (work), iPad, MacBook, iPhone both at work network, home wi-fi and mobile phone (T-mobile).

Seems like I get hit 5-10 times a day, regardless of website, link, or network I'm using.

I've searched online, cleared cookies/cache, re-booted router (at home), rebooted devices but it's seems like it's constantly popping up regardless of what/where I'm online or which device.

Yes, it's constant for me. I've even got a couple notices that I've been blocked when trying to access Yelp reviews.

They have to train their AI.

Shouldn't be regardless of the website, as they need to be Cloudflare customer for it to engage. If you're running a VPN or obscuring yourself somehow (i.e. privacy browser or always incognito), it'll trigger more checks. If your IP range in general is being noisy or hammering a site (i.e. lot of people at your office use the same site), it can happen.

Yelp definitely has very sensitive WAF rules - I've had to reach out to them to get our corporate office off a blacklist.

Now I'm getting redirects from our company system telling me Texags.com is unsafe!

Get two for Redfin and CNBC all the time. Really annoying.

I assume you aren't using a VPN? That's been a pretty consistent cause of this for me, as well as sites being completely blocked altogether. I switch to a different region, or just turn it off, and it goes back to "normal." Some sites flat out say that I am blocked because of my VPN, others just make you jump through hoops like you're describing.

I do have a VPN on my iPad to watch MLB TV. But I only turn it on when I want to stream in-region games, not 100%.

I've seen this a few times. I've actually had to disable VPN at this point. I'm not sure what's happened but NordVPN was repeatedly severing my internet connection so I didn't renew with them.

Using the free Proton VPN which is about all I need anyway throttles my internet to less than AOL speeds so killed that as well.

I have the built-in MS Edge VPN turned on but I'm not sure what that actually does, if anything.
