Why you don't clean the system and don't delete those users who registered few months ago or later and did not solve any problem?.. I think this is a good idea.
P.S. Sorry for my poor English;)

I also think so. Here is many peolple, who was registered 1 or more years ago, and didn't solve any problem. So I think it's good idea..

What if some person had been solving problems long ago. But if he does not solve them now, it does not mean he and some other people do not care about his account. For example, Ilya Nemets ( http://acm.timus.ru/author.aspx?id=12877 ) was the legend of Timus Online Judge years ago. Now you suggest the admins to remove him. It is just memories - but good memories. And I do not want my account to be deleted one day only because some newbies proposed it.

I think only accounts with very small number of solved problems (less than 10 for example) may be removed. The others should remain despite the time of the last AC.

I don't say about authors who had many solved problems, I say about those who have few solved problems and forget there accounts. There are few thousands of such authors...
