I got this message from roblox, I don't know what to do. Can someone help?

So I checked my messages cause I saw I got a new one in my Roblox Inbox, and I see one from roblox. It reads: "Hi Dev,

We received a right-of-erasure-request for the following User ID: [482478190]. Please delete this User ID immediately from all of your records (e.g. games, data stores, etc.), as this is an obligation under European Data Protection Laws. If you would like more information about how to delete a User ID from a data store, please visit our Developer Hub at http://wiki.roblox.com/index.php?title=Data_store and http://wiki.roblox.com/index.php?title=API:Class/GlobalDataStore.

Please note that you must delete the User ID from all of your records, and not just from your data stores. The pages linked above are provided for informational purposes and are not intended to provide a comprehensive method of deleting User IDs.

Regards, The Roblox Team"

I know this isn't fully related to scripting, but it is partially. I am not a full on scripter, I haven't even learned datastores yet and I recieved this. I asked one of my friends about it and he said the EU could fine me. I am honestly really worried right now and I don't know what to do. Please help!

If you have no records of this user, no action is needed.

If you can prove you have no records, you cannot be accused of keeping data without their consent.

Just delete their ID/username. You don't need to delete any data - anywhere their ID/username is, delete it. If you can't find their ID or username anywhere, you're fine.
