I think, maybe, trying to express yourself on a screen is not as easy as it looks. And you have to admit, there are some posters that will jump at a chance to make someone look bad/stupid, even though the new poster explains that they are new and don't know what they are doing.
Nevertheless, newbie postings may not be understandable to all (let alone to themselves) Some could think "deceiving/alternative motives" are behind the postings (and I'm sure there has been many) but I think it comes down to inexperience.
LIVE AND LEARN, I guess you could say
Or should it be POST and LEARN
