blacklist – Should I pay to have an IP address removed from UCEPROTECT’s backlist?

I’m working with a group that switched their TLD a year ago. I checked their old and new IP’s on MXToolbox. The last search showed their old IP address was blacklisted by UCEPROTECT L3.

I looked further and they noted it was because of a DO Droplet.
I’m decent at working with groups like Spamhaus. This site didn’t provide much info, but did say I could get the blacklist removed if I pay for it.

Should I pay to have this IP address removed from UCEPROTECT?
