Illegitimate/cloned/pirated add-ons can be used as a viral-vector.
There is a disturbing trend with fraudsters cloning popular add-ons, stuffed full of adverts and data-harvesting, and “somehow” successfully getting signed and published on AMO.
It is reasonable understandable for your submission system to be automated, but at least put an actual person in charge of reviewing ‘first time submissions’, at least for the sake of mozilla’s reputation.
We also need a way to quickly flag (and suspend) add-ons for fraud and security violations.
