Contact and fact-checking

This is a private, author-led site, so there is no separate editorial office address or feedback form. I do not publish an invented mailbox or present reviewed subjects’ contacts as contacts for this site.

Every statement in the ranking can be checked against the official pages in the sources section. If a term has changed, the current wording on the service’s own website is the reference point.

These pages do not process transactions. Questions about money already sent should go to the service you used. Contacts from its website are collected on its profile page.
