jack - i've tweeted about 4 times in the last two weeks. it's totally some kind of bs.
also, do you still work there? I was on in the early days, 2007-2010, then really got fed up with how the platform changed from people having authentic connected conversations, and just decided to give it all a rest for a while.
2 years later I logged in, and found my account had been compromised by a spam bot, and was able to delete it.
