I think this completely misses the point. The mods have told us that they get the same story from the person “in need” that we do, and they have no way to independently verify any claims about the level of need or desperation. If anything, a note from a mod would give a false “stamp of approval” to a thread they can’t validate.
In fact, I have to wonder why permission is required at all, given the mods have no real tools to determine whether to approve a request or not. I would like to know what criteria they use to grant or deny approval. I presume it has something to do with the longevity and reputation of the poster, and whether the mods think the reason for the request is valid. We just all have to realize that, just like any other place on the internet, we are getting a story that may be completely true or completely false, and use our own judgement and take our own risks.
Personally, I think if Bill Gates showed up and asked for financial support for his wife’s breast implants, it would be a highly entertaining thread, aside from the shaky rationale for the request.
