Can you explain better what exactly you do?

It seems that you use ML to pinpoint fraud (or better, undesired behaviour) in $WEBSITE.

So that could be fraud detection because they login from one country, ship to another and buy a certain combination of items.

Or that could be "spam fighting" because they create an account with X and Y characteristics and post similar things.

Am I right in my perception? (and you could use this not only for 'bad behaviour' but for good behaviour as well)
