Is there a way to limit the cart dollar amount? Having scammer problems!

I've been noticing it seems for some reason scammers or hackers are loading up the cart with like 100 million dollars in inventory. I don't know why they're doing that or for what purpose and they haven't actually placed an order but I would like to find a way to stop this. Every time it happens I block the IP range but they then just come back with a different IP. Is there a setting somewhere to limit the cart dollar amount? Any info on why people are doing this or other suggestions to help stop that are also appreciated!

There is a mod which prohibits checkout if the total amount is over a certain amount, but that won't fix what you're describing. I don't know why those clowns do that, but as long as they're not trying to check out with $100 million in stuff, I wouldn't worry about it.

You could also block all Chinese and Russian IPs in your control panel, which should cut that sort of nonsense to near zero.

same problem here for 3rd day. keep banning russian ip addresses. coming from same city.
