A person, who when replying to a message on a forum habitually says nothing more than "Me Too". Often on Fora such as email lists and Usenet, they will include the entire contents of the message they are replying to. Roundly decried for wasting people's time and, in places without broadband, bandwidth. Some Fora, with borderline support for the site's monthly traffic, will ban posts like this just to keep the site up and running! "+1" is a modern Web-2.0ish variant; while it is sometimes a legitimate idiom for "I agree this is important" , it is often used where it is not welcome.
