"Recently, an RBL provider called UCEPROTECT has incorrectly blacklisted a very large number of IP ranges. This has also been confirmed by major security and anti-spam service providers such as Sucuri. In the Sucuri investigation, an IP address was blacklisted for spamming even though it was not even a mail server. "

"Yesterday, I was browsing their site to verify something, and my IP became blacklisted on level 1 at the time I visited it, so just by browsing their site. One more small issue is that it seems that other blacklist just incorporate their data without any check."
