I had to stop using Mullvad because so many of their IP ranges were blocked or throttled by various services, it was borderline unusable as a daily driver. Unfortunately there isn't a good way for them to protect the reputation of their IPs when they don't collect any information that could be used to identify abusive customers, by design.
Maybe retiring port forwarding will help, but their IP ranges aren't going to be removed from every shitlist out there overnight.
