A long time ago, I was alerted that Freenom is/was not a trustworthy domain provider (with free domains specifically), with multiple people reporting that their domain expired way before the expiration date and sometimes redirected to adult websites.
I don't know if this is true, or if this ever happened on Miraheze, but I will test myself. If I spot any "misbehaviour", I will alert SRE to take an action against Freenom.
