I still do not get the point for this merit system, i think it was not required, instead there should have been a penalty system, for example, if someone is posting spam or low quality posts then his activity could be reduced by 1 for each spam or low quality post, i hope all the respected forum members will agree with me.
The merit system is not going away, so you better get used to it, also your suggestion does not make sense because what it is going to stop a person to just create another account and begin to spam with it? This is why the merit system was implemented, to limit the activities of account farmers which will eventually sell those accounts which then will be used to scam or spam.
