[IRCServices Coding] Nick Collision problem

[c]

Hi,

below is part of my log related to issue. Now what is strange is that we
set to forcefully change nick of a user to guest etc.. In this
particular case the user keeps on getting nick collisions. Is there any
reason for this because I cant think that there is a duplicate of the
guest username and there are a couple of these kills. I made sure the
Guest nick is not same everytime.

Regards
c
