There's no problem with wanting to "buy a rep quickly", the problem comes when you have 2 posts that have not ever actually benefitted the forum and you feel a level of entitlement for the information. I've learnt that people here generally do not mind sharing their knowledge and some are truly brilliant people but people who come in with the "I'm a busy man, tell me what the best sub is" attitude are probably likely to get their watch, be disappointed, and never comment on the forum again.
