Abd al-Monem Mahmoud, the Muslim Brotherhood blogger, arguably owes his arrest and ongoing legal problems at least in part to the prominence I gave him in an article I wrote for the Guardian (raising his profile in the West enough to make him worth going after by the regime's guys). He never complained - indeed, he told me that he knew the risks and appreciated the help and the publicity - and neither have any of the other dozens of such activists I've talked to over the years.
The flip side, of course, is the good such attention can do -- the power of media to raise the profile of the oppressed so that governments and diplomats get involved. It's a fine line: sometimes the attention hurts, sometimes it helps.
