I agree. The time element, and then the diminishing/limited individual account effect in regard to influence on REP, are some considerations worth refining and implementing to improve the REP and make it worth of its true meaning.
We must find ways to limit the extent by which a single account can raise a reputation score, and make it in such a manner as requires several acounts...that way, you are forced to engage with the community and solicit for their support, rather than relying on your alt account to do the same.
Thanks for your thoughts.
