Cloud flare, preventing logon

[GBMaryland]

No Tin foil hat.

If you are making that assumption then I’ll have to assume you lack knowledge of security engineering.

No, when you ensure third party telemetry isn’t collected (your privacy isn’t invaded), websites that use hinky 3rd parties break.

I’m gonna assume TMC just doesn’t know who can’t use the website if they never manage to create an account / login.

Cloudflare is not really a hinky 3rd party product. It's a mainstream solution.
It's a firewall product sitting well in front of the TMC servers. I'm assuming that it's provided by their Service Provider.

And if you don't allow it to determine if you are real or a bot, for security purposes, you are denied.

Trust is a two-way street. Lock your doors and so will your neighbors. And you don't get to talk to each other.
