There are some adults with dyspraxia and related conditions for whom DT is the right place to post, and from what you have written in the past, I think you're one of them. I remember one post from you in which you said that you wished you had Down's Syndrome or something that made you obviously 'different', so that no one would judge you for having supposedly childish hobbies and interests. Some people on this forum have an emotional age that is quite far below their chronological age, others have got global intellectual disabilities and find it less daunting to post on a teenagers' forum, some joined as teenagers and have simply stayed on. I've got no problem with adults who fall into one or all of these groups posting here, least of all you. You've been honest about your age from the moment you joined, you help others here, and DT helps you.
The problem comes when twenty-nine-year-old men join the forum for no other reason than to draw attention to their blogs. That could be construed as manipulative, and it's not appropriate.
