Trade.tf Bot Traded with Marked Scammer

I can't seem to find an already existing post on this, or even anything in FAQ, and I realise this is only over two Name Tags.
I have my bot set-up to decline trades with Marked Scammers for obvious reasons.
Seen here the option is checked.
Now this did work and it did bring up the guy who tried to send me an offer, but this only declines the trade from the bot, but before checking the trade.tf tab I checked my Steam to see a pending trade offer, in which I accepted. I THEN AFTER accepting the trade offer through Steam, opened the trade.tf tab and seen that he was a marked scammer. And obviously before I could decline I had already accepted.

And as soon as I had accepted the offer MANUALLY through Steam, they got sold almost instantly to two other people, and immediately out of my BP.

I realise this is my fault for not checking trade.tf first before accepting the trade.
Now tell me, what should I be doing about this? If anything at all?

Thanks, and no trade.tf's bot worked as it should, it blocked the guy's trade.
