Ubuntu Security :: IM Spam From Genuine Contacts

I, as many here, have friends on different IM accounts (and btw, so great that we have pidgin and empathy and not have to deal with 3 different softwares to talk to them) and of all that I have... which are not so many... one of them sends me spam, not all the time, but it happens and I kind of feel sorry for her so I'd like to see if there's a way for her to retake control of her account or if she can't do anything at all with it.

I have other friends in MSN but I get spam only from her and she's given up on how to fix it cause she doesnt know how to. I did a search (and keep looking for more in the web) and so far it doenst look promising (but is also because I dont know what else to do). The problem is I get messages which I know for sure are spam, cause her english is more limited and the messages are very polished in that regard.

I got this from another discussion elsewhere: "troutbot = These bots get your IM from scraping the Internet screenname and connect you randomly to someone else. While you're talking to the troutbot, they're just an intermediary connecting you to some other guy who also had his IM scraped." So far the times I get spam... the other side never answers, but if my friend is online she can. I thought that on these IM services... if you are logged in nobody else can log in with your username/password...
