Fairchij, since this issue has been clarified and people will always asses the context – or won't they? – I don't think this poses a major problem. On the contrary, it creates transparency of the discussion. Oh, it also creates transparency regarding the poster, which might be something you are interested in.

Who will read past posts anyway, unless perhaps those with a lot of thumbs? Or who will base his investment decision on a single post on an Internet forum without understanding the whole picture? (And if someone does, he'll get what he deserves.)
