Hi guys, so as the title says i have applied to 3 sig camping and all of them got rejected i don't get it ? why am getting rejected ?
There are newbies just joined the forum and have 8 or less post counts and they are getting accepted over me

first of all, it is quite hard for newbies to get into signature campaign, and second, you are not accepted because your post quality is very bad? quality is important too
That is the main reason why newbies don't get accepted in campaign, and my advice to newbie is try to upgrade your account first at least to full member and that would be the best time for you to join any campaign.
Nope my friend, that is not the main reason. The main reason is, people will flood this forum with multiple accounts and the signature campaigns will have to fork out money for people who would be
farming money. If this was allowed, people would create a single thread and have a full discussion with themselves between these accounts, while they farm the money from these signature campaigns.
We have seen a good example of this spamming, with the campaigns that allow lower ranking members.

{ Let's keep the peace, and not call them out }
Agree, thats the main reason why newbies and other low rank members cant easily join signature campaigns as of now because signature campaign itself limits or prohibited new account to join them for the reason that those low rank members would surely spam and would create alts for farming money same as you said.
