I actually think these "help me" posts are quite amusing. I think a lot of people are a little bit naive when applying to PhDs. I was no different, but the kind of questions some people ask would easily lead people to believe that they are taking the piss. But it does seem to be the case that they are asking these questions genuinely.
examples: help me get a PhD in XXXX area/help me get money for...
I would imagine most people thinking along these lines would have problems getting called for an interview, let alone being offered a position
such people might as well say:
Dear Sir/Madam,
I want to do a PhD for no particular reason other than I would like to delay the onset of the big bad world and I hear your fine institution of education has a nice bar. I sleep in till late and usually play video games for the rest of day so i am only available for interview at the most inconvenient time,
regards, Joe Smartarse
