Thanks, @ianfontinell. That seems reasonable though you could just as easily swap new & old in your approach 
(redirect gaytorrent.ru to gaytor.rent instead, though I suppose that won't work for the forum since community.gaytor.rent doesn't exist yet.).
In any case, I think this is a small bug that will need to be fixed on the path to full migration to gaytor.rent.
I'm experiencing what looks like a bug with redirect link generation.
When looking at a torrent on the old site, gaytorrent.ru, a redirect link to gaytor.rent is listed at the top of the page in a green box. While the link appears to be correct, when it is clicked, the browser opens a URL that has the id parameter listed twice, like so:
It's not clear to me why this is happening just yet, especially because simply copying the link address from the green box yields the correct URL (with the id mentioned exactly once).
