It was only a suggestion to help people here who's desperate to find a cure for EC. I've seen many people posting their "cure" only for them to find out they've not fully healed yet and that "cure" wasn't working like they thought. We can't go on everyone's word here. If you're cured, then why not prove it?
Why would you take a before pic? Because you know there's other people with the same condition on forums like for years waiting for some good news and this is a way to prove your claim. If you truly cared about helping others, then this wouldn't bother you.
