This is just spam, but a little different from most. This person posted many spam posts to various groups at the same time several hours ago. However different things are offered to different groups that are more or less related to the groups, such as a wine device here. In alt.hvac he described a bolt together steel garage. A person responded that he should stick it up a certain body orifice, which I will not name to avoid offending some. This might be impossible for a garage, but might be possible for the screwpull he offers to this group, especially if it is a lever action model..
