In ptp you can only buy an invitation. They are very careful with the people who enter the community.If you count lasts a lot or a little, it depends a lot on the inviter. 1- If you send an invitation from one end of the planet to another extreme that usually attracts attention the best thing is to get an invitation from your same area. 2- If the person sending you the invitation sends many from the same account, it increases the risk of banning for you and the other guests from the same account.The invitations of ptp with costly not because they are difficult to obtain are it because nobody wants to risk losing the account.
@rock123 I hope this helps a little
Note:In ptp many months ban more user than they enter.
