..i assume this should be easy for experienced tcl wolfs. :)
Is it possible to create a tcl snippet that will temporary (say 30 minutes) kickban person from the channel in case he/she post empty string (only spaces). For example user can post "_blah___blah_" but can't post "_" or "___" or "______" etc where _ is space. If user attempts to do so he gets kickbanned from the channel for 30 minutes with message "Please don't post empty strings. ~30 minutes ban."
Another solution might be that bot puts person on ignore for 30 minutes with the notice "Please don't post empty strings. ~30 minutes timeout."
This is all related to certain trivia bot problems where posting of empty string might allow cheating.
