Personally, I use a network that supports chanmode +R and umode +R, so I don't have spam problems.
Secondly, it's not very wise to asume that everyone has access to a 24/7 bot. It's also not very wise to assume that even the majority of users that join your channel will reply to such a test. It's been my experience that the average user don't even read the topic or on join messages.
Thirdly, I personally would find somewhere else to chat other than your channel because I don't want to be bothered with joining a channel... taking a test just to be invited to another channel (might have something to do with the fact that I ignores all invite anyway
)
If all your doing is getting past a +i chanmode .. it' is just as effective to set your channel +k and give your friends the chankey. I would assume that only your friends will be interested in going through that whole mess to startwith.
