On the one hand I can see why topics where people gracelessly demand a given game can be annoying, especially when there have been a number of them in quick succession.
On the other, Jack is dead right about Paypal being arses in many parts of the world, heck I've recently found their charges for credit card transactions are actually illegal in the EU, but they're doing it anyway so they can get at people's bank accounts, plus even if your not living in a country where paypal are being annoying, there might be many other reasons you can't afford a game, and as Aaron said, better to have a game bought for you and support the developers than resort to piracy.
Back before the massive forum crash that rolled us back from August, there was discussion of directly setting up a "gifting forum room" where people could request copies of a given game, or could alternatively give away copies of a game if they wished.
Having a specific place for these sorts of transactions might be helpful, both in showing potential requesters the best way to make requests, and for clearing the rest of the board. plus then topics could be closed once a request was fulfilled.
How such a room on the forum might work, and what the rules might be I'm not sure at this point, but maybe that would be a plan worth considering?
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
