This is pretty Funny. I pissed the nerds off at Digg for posting my website links in commends. Did this ever happen to you?
No that never happened to me but I never post my website links in the comments. Does your website help explaining what you want to say in comment?
I wouldn't lose too much sleep over it. From what I hear Digg traffic doesn't do much but crash your servers. Besides, you can just open another account (or 5) and continue on your merry way.
but does it convert into sales or clicks and do they ever come back? If not then they're a waste of time and energy.
Until they ban your IP I find Digg traffic is useless, but having Digg to your page can get you indexed incredibly fast and get great Google rankings for that page (at least for a week or so).
