Fair enough
At the time I was hosting my signature pic on the same domain (have now swapped to the Steam one), so a little more thoroughness might have caught this? Just saying.
I never had an image removed, because the domain name I was hosting on was obviously my own, lum.co.uk, matching your username.
If that really is your domain then why not create a subdomain, like http://hey-ocuk-mods-this-is-my-own-domain.mohache.com/ and put the images there?
These days I just use imgur.com for this thread as it's free to use and saves my bandwidth bills.
