Gemini “cracking down” on legit users?

After my recent round-the-world trip, I get home to see this in my email account:

Your Gemini Account – Action Needed

A review of your recent account activity showed regular deposits of fiat and a one way trading pattern where you deposit funds, convert it to digital currency, and then withdraw. This may be indicative of business activity. Could you please provide an explanation for this pattern and also the source of funds for the referenced activity?

Additionally, from the end of July 2018, you have only logged into your Gemini account from XXXXXX and the XXXXXX. Can you please verify your current residential address? Please upload a new proof of residence document showing that address. Please visit http://exchange.gemini.com/upload to upload your documentation.

WTF is this Gemini?!
