It advertises to all and sundry that the wearer is totally ignorant of what a clan badge is, who it belongs to, and how it is properly displayed or worn.

According to Lord Lyon Sir Thomas Innes of Learny in Clans, Septs and Regiments of the Scottish Highlands (page 521):

"The Chief's 'strap and buckle' badge... is worn by all 'his clan', not as 'theirs', but as showing they are his clan and following. The crest is legally an armorial bearing and the property of the Chief or Chieftain."

Now the Chiefs, speaking through the Standing Council of Scottish Chiefs, have indicated that the "clan badge" should be worn as a bonnet badge, or a brooch, or as a decorative item applied to certain licensed items-- sgians dubh, for example. And that's it. (Individual Chiefs may have authorized some clan officers to wear the "clan badge" from a ribbon worn about the neck as indicative of their office within the clan-- which is of course their right as a Chief-- but as far as I am aware none have approved the wearing of their badge by their followers in imitation of one of Her Majesty's Orders of Merit or Honour.)

So, by taking a clan badge and attaching it to a ribbon, and then wearing it in imitation of an order of merit or honour, or in an attempt to "pass oneself off" as an officer or functionary of a clan, shows either extreme ignorance, or a conscientious desire to deceive people into believing that the wearer is somehow entitled to some sort of deference to which he clearly is not entitled.
