I have no idea why someone would give this organization's site a bad review, other than out of hatred for Christianity. This is a very reputable organization and their website is absolutely fine to use. They do not send spam or anything else people would want to avoid.
This site is a Christian related site sharing and understanding God and His Word. I have received daily devotionals from them for years and find them completely reliable and honest and a very important tool toward my Christian growth. I highly recommend this site for those who care to expand their knowledge and service to God and His ministries.
