I'm being falsely accused of being a "Scammer Alt"

Yesterday I went to sleep and decided to leave my steam on with a tag saying I was asleep. Today, I woke up and got these messages from someone I've dealt with in the past (I bought buds from him). I have no idea who the person he's talking about was until I did a friends list search and saw I had him tagged as "buying buds 6/16." I have no clue why I'm being accused of this because I've never even traded once with this person. I definitely don't want to be tagged as anything because I'm a legitimate trader. Anyways, I know not to deal with this person in the future, but what can I do at the present moment?
