fb acccount to write PM

hello
I need to send about 500 PM to fanpages in my category
FB always block my account after sending about 10 messages (I used private proxy and new firefox profile for each account)

does anyone has good method to sending PM without facebook ban ?

if your text is the same + same url

you will be block faster (around 10 messages)

Its depends proxy and what type of message & url

Private proxy does not mean, its a good proxy. it can be soft blocked.

with soft blocked proxy you can send few after that Block

if your message looks spammy then after few block

try to send not spammy message & uniqe
and if you send message with a url its too dangerous after few block.
