Resolution to refrain from blocking spam accounts

The edit filter, despite a rare false positive, prevents the spam edits from being saved. However, some editors blocked the accounts that triggered the edit filter. My question is should we simply ignore these accounts so long as the edit filter is taking care of them or should admins block them?

Ah, now I get your point. There is no doubt that their edits should be stopped, so I think that we won't have any harm on doing it. Maybe you are worried about flooding recent changes with block log or about the time that users would have to spend by blocking accounts (those are the only issues I can imagine). However, when we block them, we avoid more account creation (due to autoblocks) and prevent any further edit, which might be useful in case they change their edit pattern to another not filtered. Just some thoughts.
Anyway, it is a good question. (Happy new year to everybody)
