Nobody is perfect with their grammar usage, but there are just some people that have little, in any, regard for the reader. That in itself speaks of apathy and selfishness on the part of the poster.
Spending an extra 2 or 3 minutes cleaning up one's post to make it readable, with the use of punctuation; spelling correction; and paragraph usage; isn't asking all that much.
