Err, same issue as everyone. Haven't been able to download anything off torrents for a while now. I got a 4 Mb/s plan to download stuff, and now, I will either downgrade or switch. Unless they remove the tracker ban. I do intend on giving them about a week, (my exams get over then) at which point I will not be able to survive without torrents. Also, they have been throttling my downloads for a while. I was getting about 100-150 Kb/s tops, as opposed to around 500. I was blaming it on the seed/leech ratio, but now I see that isn't the problem.
my connection only gets throttled from 7pm-9pm , although i never use sites like link-removed or link-removed as nearly every isp knows about them plus link-removed has real speed issues on new or very old torrents.
i suggest you to move to another isp if airtel doesn't solve this after you complaint . i'm ok with them throttling p2p for a couple of hours but if they are throttling for major part of day then you should probably move to another isp .
