I think the quickest way to dig yourself out of ratio jail is to make a financial contribution to the site (see https://www.gaytor.rent/donate.php for the details on this). You can do the math to see how much upload credit you need to get above the 0.8 penalty line. You also get the satisfaction of helping to keep this site operating: computers, software, and bandwidth aren't free.
When you do get download rights back, there are a few things that can help your ratio:
A good way to increase ratio is to download only a few files from a new, large torrent--maybe 10% or less of the content. Those will often download quickly, and then the tracker system will hook you up (!) with other users who are looking for that material. The results can be astounding: here's a snip from my uTorrent client showing five torrents that I've done this way:

Even if you have a ratio warning, grabbing 5% of a new fan site collection will pay off for you even if you don't want the content. For example, on that one at the bottom of the list I only selected 5% of the content, but uploaded nearly 66 times that content. The only drawback here is that a torrent from which you haven't downloaded all of the content will count against your number of available download slots...so depending on how many slots you have, this could be an issue.
Keep your computer on all the time, with the torrent client running. I rarely turn my computer off, because on/off cycling puts a lot of wear on the machine.
And finally, try uploading some of your own material if it isn't already here. If you downloaded something from another site, or from here a few years ago and it's gone dead, uploading it will usually give you 2-3 times the file size in upload volume--sometimes much more. I think you can still upload new material even if your download rights are gone, but a moderator might want to weigh in on this if I'm wrong.
Good luck and best wishes!
