Your all comments are reviewed by the Link Owner. If he thinks that your comment is non-genuine or spammy or irrelevant then he may reject your comment. If your comment is rejected by Link Owner and your account was already credited for creating that comment, then you are penalized with 2.00 Bin Points and 2.00 Bin Points will be deducted from your account.
We want to keep this Bin clean, so this feature is required. Comment rejection is a right of Link Owner and A1B.in never interfere in his decision.
