It probably does nothing directly.
It will just feed the data-point into an anti-fraud/anti-spam system along with everything else.
And the anti-fraud/anti-spam system is probably a machine learning black box. It will learn if this data-point is actually correlated with naughty behaviour, and what other factors are usually correlated.
I'm wondering if eBay displays a fraud warning, or pretends to allow the transaction to occur (shadow bidding?), or just hellbans the account being used.
For shill-bidding farms, the obvious counter is to move remote screen access to non-standard ports, or move to headless browser operation via other scripting methods.
