WP.org download counter spam

[hallsofmontezuma]

It looks like some plugin authors are spamming the download counts. Every now and then, a plugin mysteriously has thousands or tens of thousands of downloads in a day.
It's generally blatant when it isn't legitimate. ie, a brand new plugin with no or few ratings, no forum threads, etc. This is obviously done to have the appearance of being "popular".

Is there something that can be done to limit the download count to IP per timeframe, or some such thing?

Plugins are manipulated to top 5 and are containing spam code.

Some of the plugins with faux stats show affiliate ads in backend:

Download counts have always been limited by IP per day.

Sadly, the implementation was backed by a MyISAM table that filled up :)

The implementation is now backed by a InnoDB table that should be able to soak up a lot more data.
