If you disagree about rep pay the subscrition fees and become an elite member then you can negative rep people for rep'ing for no reason.
Personally i think your reputation should preceed you, that is if i trust and know you i will already hold you in high reputation regardless of your rep bar and status. Rep is fun and part of the site, how one gives and gets rep as oppose to another is none of my buissness, rep means nothing to me neither dose someone elses rep, only good advice, talk and friends is important on this site.
Why worry about the rep bar, i rep noobs who seem intrested in weed and show some passion in the hope they will carry on being part of a great site. If they wana get rep'ed up then let em, at least they will post and we can all have some good times! Peace
