OP says that the campaign goes until december but comments says it's over
can you confirm and update OP in case it's over?
cheers!

Likely had something to do with the abuse, but mainly because it wasn't a way to get it to a wider adoption.
Well, I've discovered Semux just because of the sig campaign. For a while you could see it everywhere. But I agree that to keep it on all the time creates tollerance and less and less attention. Perhaps they should run periods of sig campaign now and then. On and off - most effective strategy IMO.
