The damage for removing a valid score from a known cheater is that they may be robbed of a legitimate score. The damage of not removing an invalid score is that that score may be impossible or require superhuman skills (i.e. TAS) to attain, thus forever removing that category from competition. This lopsidedness - and don't get me wrong, a healthy dose of schadenfreude too - makes me strongly believe proven cheaters should be stripped of all records.
