I've recently found that when Quoting someone or in my case being quoted someone can actually alter or completely delete you're quote and type whatever free text they'd like thus making it look like you originally posted the contents. I don't believe it was done out of spite. There's been times where I accidentally hit the quote tab and can't get it to go away so I'm thinking maybe out of frustration another member just deleted my text and put their own to get a message across.
The problem was the discussion was with a new member who didn't agree with the contents of the reply (a reply quoted in my name that I'd never in fact ever wrote). I've reached out to that member and personally apologized to him letting him know that I believe there's an error going on. I'm not sure if it's limited to the mobile version or its on both the mobile and desk versions. Hope this can be resolved soon. If an admin can PM I'd give a bit more detail.
