Is there any chance that a set of rules could be implemented to prevent abuse of the endorsement system?
It seems that currently, anyone can endorse anyone and there is no restriction.
I can provide an example of what appears to be abuse of the system, however, I am against naming in public so please PM me (Dani/Deceptikon you're the only guys I know reputibly)
I would like to propose that only active contributors can endorse and that this should have a minimum threshold. You should also only be able to endorse if you have a minimum amount of reputation. This should stop at least difficult enough to abuse that it isn't worthwhile.
Unfortunately, as it stands, the endorsement system doesn't appear to be trustworthy.
