China jersey company?

I recently received three comments on forum posts from someone calling themselves chinajerseys that may have messed up my computer and or internet connection. They contained English words, but not in any useable order, and after deleting them my connection crashed. Three days later, I'm finally able to send and receive. Could you please look into this user to see if they are valid. Also, so that I don't have to go through my email to delete all of the Vital responses, how do I stop being notified by email. If I care about a forum topic, I'll check it through the website. I hate to call anything Vital spam, but it's really getting annoying. Thank You.
