Reset Custom Title and Custom Avatar

[Kaelon]

Hi there,

I asked this over at vB.com but realized that it might get a more appropriate response here.

My community has a paid subscription program that grants the subscriber usergroup with the privilege to select a custom avatar and use a custom title (among other things). However, when the subscription expires, and the user is moved out of the subscriber secondary usergroup, they still keep the custom titles and custom avatars.

Is there a way that custom titles and custom avatars can be removed/reset for non-subscribers upon their deactivation?

Are there any mods for this? If not, are there a couple of easy queries that I could use to build my own mod?

Thanks!
