I can't add friends on Facebook .. WHY ??? is this a permanent block on sending friend requests ?

Question

I can't add friends on Facebook .. WHY ???
is this a permanent block on sending friend requests ???
few months back :
I was prevented (for 2 days) from adding friends or sending messages to those who aren't my friends ..
When the 2 days ended : I sent more friend requests and then I was prevented (for 4 days) from adding friends or sending messages to those who aren't my friends ..
When the 4 days ended : I sent more friend requests and then I was prevented (for 7 days) .. then (for 14 days) .. then (for 30 days) ..
now the 30 days period ended ..
and I tried to add friends , but when I sent the first friend request : facebook gave me an alarm message that my friend requests are blocked for 2 days ..
why ????
I am sure no one reported that I am adding someone who I don’t know , because (facebook gave me an alarm message that my friend requests are blocked for 2 days) just few seconds after I sent the first friend request after the 30 days ended ..
ok I waited for the 2 days and right after the 2 days I tried to send a friend request ,
guess what .. after few seconds : (facebook gave me an alarm message that my friend requests are blocked for 4 days) ..
and I waited for the 4 days and right after the 4 days I tried to send a friend request , guess what .. after few seconds : (facebook gave me an alarm message that my friend requests are blocked for 7 days) ..
What the hell is going here ? is this a permanent block on sending friend requests or messages to those who aren’t on my list ? what should I do to solve this problem ?

after the block is over : when I try to send a friend request , they block me again instantly without any reports or rejections of my friend requests ..

why ?????????????

is this a permanent block ?

just review my case

Answer 1

it happens when you send to many friend request at a time you keep sending while ones sent before havent been accepted it happens or when someone clicks the hide on your request because they dont know you and when that happens also to many times you get blocked

Answer 2

no its not permanent, the time will be exceded every time u like to add those peoples u dont even know.. if u add those peoples whom you dont hav mutual frnds ar any link facebook mark it as spam.. so if u try to send again and again it will reach to 30 days for sure..

Answer 3

if you send too many friend requests this happens.
