What user agent does Overture use?

when they ping your page for quality

[Bewenched]

I recently banned some bad bots and very questionable user agents in our robots.txt file, but now when I got to add a new PPC ad it says they cannot because their bot is banned from my site. I've written them several times to get the name of the user agent so I can take it off the "bad boy" list, but I've gotten no response.

Thanks in advance.

Overture changed its name to Yahoo Search Marketing. I believe the current agent is YahooYSMcm. Let me know if that works for you, if not I'll double-check my report.
