My bank blacklisted me from their online banking portal because of a "suspicious IP". After submitting a number of automated requests to my bank's new security website (a company in another country and only available in a different language), I found out that my IP was marked as dangerous because I ran a Tor service at some point in the past. I hadn't been running it for months but they still had my IP tagged as potentially malicious which was enough for my bank to distrust my ip. I should also note that I also had a static IP back then, which due to this ban, I subsequently disabled. In the mean time I've moved all my external facing (mostly Raspberry Pi) services to VPN and plan to finally re-activate static IP.
