The trick is to use the most normal hardware, software and network connection you can think of. Which I assume you aren't doing for ideological reasons, which is fair.
How do I know this? I have received reports from various websites (and manually queried some public block lists/RBL/etc.) that my IP range was blocked due to all sorts of different things like open proxies, CSAM etc. even if I've never visited that site before, and I know just from being a neteng that that such traffic is not originating from my devices/router and I don't have any observably compromised devices or suspicious traffic when monitoring it.
