Grrr... the comment system thinks I'm spamming it now, since I've been trying to inform people of their mistake. If you have time, energy, or a lot of watchers PLEASE spread the news! I've been trying to get the message out to everyone who's mistakenly watched this account back.
!MoscaIsAFgt (https://www.deviantart.com/moscaisafgt) is not a friend or newbie. It's a bot, trying to get a lot of pageviews and watch-backs. It's all in this article- http://news.deviantart.com/article/124258/
Please, don't encourage this behavior by watching or thanking them.
To remove their watch from your account, go to this faq- FAQ #68: https://www.deviantart.com/help/68 - Can I remove someone who is watching me?
I'm really sorry you got hit with this.
