Who cares about some arbitrary "ratios" displayed locally in a client?
Of course I posted my tip for those that care about their ratio, not for those that don't care. ;-)
Indeed, so in order to avoid a "bad ratio" just share the blockchain data torrent until you uploaded at least as much as you downloaded.
Not necessarily. If you had a ratio of e.g. 2.0, you'd have to upload the file twice to get your old ratio back. For people with an average DSL connection, with typically fast download speeds but low upload speeds, that's almost impossible to achieve, especially when they prefer to go about other torrents. So, using a different torrent client exclusively for the blockchain torrent, is a simple way to keep your old ratio.
Esp. if you use torrents on a regular basis you should just keep this one running for a few months. Everyone seeding is increasing its speed for those downloading it. If you care enough about other torrents to get a 2:1 ratio, why not about this one?
