Re: argh!
When the soj counter has started to go up quickly, you usually have a minute or two to get on the right server, so in most cases it's too late then to get a new game on it. Also, a big portion of the server will be occupied then, by those who paid the soj sale, so the chance to get a game on it at that stage is rather small anyway.
The typical way of getting dclone games (apart from participating in soj sales) is checking the usual web sites, to find out how many sojs have been sold since the last dclone walk on each server, getting a game on the most promising candidates and then waiting a day or two. I doubt that the organized sales heppen on the server with the highest count (it will be full of moochers like us

), but on #2 or #3.
Anyway, I'm not going to waste electricity by letting my computer on all the day just to get a soj or two per month. When assuming that it needs 100W constantly, that's 2.4kWh a day which is about 60c a day here, respectively €18 a month... and not to forget, the computer will suffer from wear and tear as well. Last but not least, games often crash soon after the walk, so to be really effective, you either have to be watching all the time or you have a kind of hack which triggers an alarm or a bot which kills the dclone.
I will to none of all that. Getting dclone games in that manner is a waste of resources.
