Yea deal with the individual stongly, KIIL EM, like they used too. It is nice to be able to see if the people you correspond with are looking at your information. As far as people abusing the counter the ip can be blocked or the user can be banned from QRZ all together. There is a way to solve the problem. You can send a cookie to the machine that is making the hit on the call.
Software then can tell if the person has made that hit recently.
Don't allow any counts on machines that accessed within 24 hours. Astute programmers can get around this. So in addition, you may want to track the IP address of that machine also. I personally never paid much attention to the lookup count numbers, they didn't really mean much to me. I don't mind them being there, but if their presence is going to affect the performance of the server because of the abuse by individuals that feel they have to have the highest number, no matter what it stands for, then I have to agree that the best decision is to take them off.
