Preventing other plugins texturize mine?

How do I prevent other plugins to format my plugin’s returned html?

I removed the filters texturize and wpautop in every imaginable place, even when not dealing with content, and my content gets re-formatted anyway.

I found out it happens in some blogs and not others (all 3.3.x) so it must be another plugin texturizing mine. (mine adds code to the content’s page)

Thanks.
