Being on the PBL is normal. All addresses allocated by DHCP should be in this zone.
Likewise, the SORBS DUHL is also a PBL - again identifying IP addresses that are allocated by DHCP.
Spam Rats Dyna appears to combine two functions.
Identifying IP addresses that have been seen trying to authenticate with too many invalid users, and also conform to naming conventions which suggest a connection allocated by DHCP
Protected Sky doesn't say a lot apart from stating it rates IP's based on the amount of spam seen from that IP. According to MXtoolbox should spam levels drop, the IP is automatically delisted. There is no manual removal process.
All of these lists are designed to stop Spammers sending addresses directly to a mail exchanger. If you are a normal user submitting email through a server recommended by your email provider, these blacklists will have no impact on you sending email.
Likewise, these lists are not used to stop you connecting to Web sites either.
