I'm not an active SE user any more, so apologies if this is the wrong place for this. I couldn't think of anywhere more appropriate to post it though.
SE user MediaGirl is promoting the ExpressionEngine proposal on Area 51 via Twitter spam to SE users. Screenshot below:
I assume this is against the rules for Area51? Messaging me about it was random, as I've barely used a SE site in months, and have never mentioned this EE CMS that it's for. I can't speak for balpha and samthebrand, but it seems to me that Joel wouldn't be interested in discussing a commercial PHP CMS either, so that message also appears to be spamming for support.
The site is currently second in Area51's hot ranking, and it seems a significant portion of it is down to this user's referrals, as she is topping the list with 64k total rep and 24 referrals.
