Both of these match existing UAs, except for the single-quotes the UA is wrapped in. I checked and this was not a parsing error on the part of my log analyzer that's how they are the in the raw log files.

New? Old? Dunno. Old, unpatched UA; no graphics, just html. Just like a bot. A bad one...

Y!J-AGENT is when someone posts your URL in Yahoo! messenger and is verified (for lack of a better term.) I've been seeing this UA for a long time and don't see it as a threat if IPs check out.

[GaryK]

Do I understand correctly that if, for example, you and I are chatting via Yahoo! Messenger and I send a link I'd like you to look at, that Y!J-AGENT is monitoring our chat and will go fetch the URL? If so, for what purpose, because I'm not sure I understand what you mean about the link being "verified."

[keyplyr]

Something like that, although "monitoring" might not be the best term; might just be what implements the hyperlink. Not sure.

My older post here [webmasterworld.com] was removed for some reason.

[GaryK]

So it's clicking the link that causes validation not just me sending it to you?

[keyplyr]

Gary, I'm not sure. Last year I thought I had a pretty good idea exactly what it was and I posted in your other thread at that time. That post seems to have been removed. About all I remember from the research was that the UA showed in my logs when a link was posted in either Yahoo! Messenger or some utility that's associated with that service, like a bookmaker or a social link sharing tool. I don't use these types of things, so I tend to forget the details quickly.

[GaryK]

No problem. I'm curious so I'll install Y! Messenger and see what I can learn. Normally I stick with MSN cause I can chat with Y! users that way.
