ok man you are talking about important subject in torrent praivte sites , first of all you have to know what kind of content you are looking for coz it depends what you want

for example if you are huge fan of TV shows you go to (BTN - MTV -BitmeTV - TVV) , or Movies (KG -PTP - CG - TEH ..) , Or HD and blu rays ( Tik -BitHQ - HD torrents - HD bits ) and etc ... with others category

now for to way how to get it there there is 4 ways :

1 - If you no a friend who has Account there and invite the he can invite you

2 - According the requirements whom has other trackers to Accepting new Accounts to others

3 - If you can get an invite as Give away like this pretty site

4 - Request that you want to buy invite with money



ok the first 2 are the safest way as everyone knows , If you want to get in BTN and you dont have any friend there I think the best way and I recommend you number 2 and last chance is number 4 .

in the end there is diffirent hard to get ech Tracker it depends on Tracker it self if is it high like (BTN - PTP - HD Bits)

anyway good luck to rech your goal BTN or what ever
