In the past, I've seen people request invites for other torrent sites, and have been falcon punched, etc. because of that, but as far as our rules go, I think this is perfectly fine.
Not sure how many people have heard of the T-I community, but it's a great place for getting invites to torrent trackers. That aside, there is a very friendly community. T-I is a forum-based community and not a bittorrent tracker
, with the main purpose being the giving away (sharing?) of invites. They have a few strict rules (and lots of people get banned for violating those rules, including racism, swearing, trading, etc.), but it's a valuable place to have an account.
To use T-I, you have to be "Repped in". All new accounts will start in the "Starting" user class and will only have access to the default 3 forums, one of which is the Introductions forum. You're required to post an introduction, and if people like what you've put, they'll give you a rep and you'll have access to the rest of the forum. This process takes time and could take days, so be prepared to wait.
After gaining access to the rest of the forum (unregistered users can have a look to see what's available), depending on your post count, you can ask for invites in the form of a request (use the Request Invites forum) or ask for them in a Giveaway, when other people are giving such invites away. Either way, you'll need to be repped in before you can do that.
I'm a member at this site, not saying my username, because you are required to use a different username than on trackers, but to give some personal experience, I've gone from having an account on What, Demonoid and BakaBT to having accounts on 11 trackers now, so if you're after invites or something, do check it out and stop posting thread asking for them here.Torrent-Invites.com
