Oh gosh anon, this is a tough situation to be in (and sorry I’m getting to it a little late, we had a busy night last night.)

My advice is that since they have accepted your commission, you should just not say anything, and let it pass.

It’s possible they’re the type of ‘dni proship’ who just has it there so they don’t get harassed by antis.

If it makes you uncomfortable to interact with them after this, I would just say to let the completion of your commission be your last interaction with them.
