For some offers, advertisers check the leads before you can receive your payout for them. This checking period is usually called ‘hold’ and can vary from 0 to 60 days.
To check the traffic quality, advertisers make sure that it complies with the offer terms and doesn’t abuse the program conditions.
If an advertiser discovers any terms abuse, or finds some traffic that doesn’t suit them, they have the right to refuse a payout. Note, that the CPA network doesn’t take any responsibility in such cases.
