My doubt is bit different. If we replace [~2] with user name in text area, then on entity preserve we will have to replace it again with actual value
So it is there any filter format that we can use it just to replace text [~2] with relevant user name so actual user name will be intact and there will be less processing.
I'm digging codebase of opensocial to get some more insight around this.
