I think some changes on the MSN servers cause the "has you" option not to be reliable anymore.
When I view the info of a msn buddy, on many (mostly new added) contacts there is written "Has you: No"... this has caused some confusion among my friends, who definitely have me on their contact list, so I thought I warn everyone here not to get into an argue with their friends
As of yet, I couldn't find an exact pattern, when it shows that the other contact doesn't have you on their list.
A ticket has been already filed to the pidgin devs...
