At work we are a few programmers behind one static public IP address. I have introduced a coworker to Stack Overflow (SO) and of course another one uses SO regularly. Although we don't have much overlap of fields, I wonder what I should do if I ever do encounter a coworker on SO. Should I ignore his SO posts online, completely?
My concerns are that our shared IP address might get flagged if we respond or upvote to questions and answers. I am aware of other Meta SO questions regarding the ethics of the issue, which I am not asking about. I care only about suspensions, not about reputation.
I asked here about SO but I think the same would apply to any Stack Exchange site.
