I don't recall thematoweb ever actually being affiliated to moodle.org or any of the partners - simply a site providing a tool for creating themes for Moodle 1.9, so i don't think a tracker post would help.
'Themato is an initiative to promote Moodle and the ease of using it. It is carefully curated and nurtured by a group of enthusiasts from the moodle community.'
Possibly the previous owner and other users of the thematoweb site may still be active on the forums and will see your warning about passwords on multiple sites though.
