I have several flickr.com picture-accounts and successfully placed a flag-counter in the comments section of several pictures. Today, I opened a new picture account, got a new flag-counter link,   

<a href="http://s03.flagcounter.com/more/5z6W"><img
src="http://s03.flagcounter.com/count/5z6W/bg=73C7FF/txt=000000/border=
ED4F15/columns=6/maxflags=100/viewers=0/labels=0/pageviews=1/" alt="free
counters" border="0"></a>

and posted it in the comments section of my latest picture of my Flickr photo-stream. When I open the picture, the flag-counter does not appear in the comments-box and when I edit the comments-box, I see this:
<a href="http://s03.flagcounter.com/more/5z6W" rel="nofollow"></a>

Most of the flag-counter link is gone, and [ rel="nofollow"></a> ]  had been added to what remains....

Is this some kind of code that Flickr.com uses to block posting of the flag-counter ?

Does anyone know any way around this?  If so, please post an example of how I should modify the flag-counter code to make it work there.
