More people (at least for fulltime irc'ers), actually asked for and/or like it, than not. It comes down once again, to personal preference, and everyone is going to be different. That's why there are always options. Besides ignore, if your irc client is any kind of decent application, it will have other filtering options, including filtering out stuff like fml, etc. Again, you can always ignore any individual as well (including any bot). Hell, my personal annoyances are the pages long convo when they start about shit like FFB, or erepublic. I don't go start enforcing my personal preferences on everyone though, by adding a kick and/or kickban 'badword' filter, etc.
Back to my post (previously) again though, there is not any problem. Having separate bots gives you yet another option... ignore the one you feel is for "spam".
Having an alternate channel makes no sense, to be honest; we don't have enough users/traffic to warrant it. It'd be a ghost channel, like the others are (#trivia, #radio...).
You could potentially change the output of the bot for certain functions to either private message them a response or i think you can notify a single user in a channel.
