I wonder how exchanges know each other's addresses? Don't they tend to use a new address for every incoming and outgoing payment?
Do they have private API's to verify addresses?

They are fairly easy to pick out simply based on the way money flows in and out of the addresses. Also, they become known over time as customers share them then they are eventually labeled by companies (exchanges included) performing blockchain analytics. Many of the public blockchain explorers show labels for popular addresses. I've seen labels on big exchanges, Satoshi's coins, seized silk road coins, coins from hacks, etc.
Which exchange were you withdrawing from?
To be fair it was a regulated stable-coin issuer based in NY where i was redeeming stable-coins for USD, so the strictest of all AML was to be expected. I was just surprised the tech is already in place for a travel rule for crypto. If i would guess it would've been a company like chainanalysis aggregating the exchange data to enable this.
Sent over 20 transactions from US exchange -> US exchange and no problems.
Sent a single transaction from my unhosted software wallet -> US exchange, and got my account locked. Questioned on everything including my employer's information, had do re-do advanced KYC, source of funds etc. (The unhosted wallet was funded from an exchange which makes it stupid, and i didn't use any coinjoins or anything).
