STAMP- So please stop asking. (stock)

This stamp is free for use on deviantART via its thumbnail code.

In a similar vein to a previous stamp, it's very frustrating to be asked if my stock (specifically my drawing bases) can be used. How much clearer do I need to make it for some folks? I'm adding a variation of this stamp and others to the Artist's Comments of my bases, but I have a feeling even that won't stop me from being asked "Can I use this?" Are there really a lot of stock providers out there who demand that folks ask before they use a stock image? That seems to defeat the purpose of posting stock images, IMHO.
