See this is what terrifies me about gating anything behind an X login

That's not a calendly link, it's a malicious x permissions link - it INSTANTLY deep links to the x auth page 

2 taps and your X account is gone with zero context of what's happening 

So many would fall for this before they realized

Mini apps will eat the internet | building /clankermon $clankermon

Clankermon

Not to mention X support is now none existent if you don't pay thousands of $ - even then you see gold tick subscribers have to create a scene on the feed (if they can) to attempt to remedy anything

btw, even if you pay x thousands for gold tick, it takes days for them to give you any support. their biggest mistake is that if your account is taken over, you can't dm premium or the org contact. and then when you  use the form, it just goes to some really terrible folk.

its interesting you got this kinda of crappy email. a lot can also be stolen by literally social engineering your x account (even if you have 2fa on, they will happily disable it).

glad you avoided this particular scam
