The meaning of "referrals" in the message text in MediaWiki:Top-fans-by-category-title-referrals-count in unclear. Translations to various langauages are incompatible. Please document: https://translatewiki.net/w/i.php?title=MediaWiki:Top-fans-by-category-title-referrals-count/qqq&action=edit&loadgroup=ext-socialprofile-userstats
"referral" in this context means referring a user to the wiki via a specialized signup link, such as http://example.com/w/index.php?title=Special:UserLogin&type=signup&referral=Foo. If the referred user signs up via this link, the referrer (User:Foo, in this example) may be awarded some points as a reward (if set so in the site configuration); the amount of points is specified in $wgUserStatsPointValues['referral_complete']. For the referral stuff to work properly, you need at least one separate extension, [[mw:Extension:NewSignupPage]] (based on the old LoginReg extension) to add the hidden referral field to the signup form. In order to generate and mail out these specialized signup links, you should use the InviteContacts extension (see [[mw:Special:Code/MediaWiki/84110]]), but admittedly that extension is (still) a work-in-progress.
