Piwik referral links

Gentle men,
I’ve noticed that the piwik codebase now includes referral link. An example is the referral link to Maxmind on the visitor page:
hxxxttp://xxx.xxx/piwik/index.php? module=UserCountry&action=adminIndex&idSite=1&period=day&date=today


Question. Who is this aff iliate xxxx going to and has this been published? If this mxoney is going to piwik itself and is accountable then thats great. Otherwise. …

P.S. WHy is the word mone y censored ?

It goes to piwik project of course, so far it generated 360$ of revenue (about 70$ per month) so it’s very small (but still useful!)
