The redirects manager picks up a tonne of 404 errors.
Most of them are spammy, I would guess, attempts to find out what system I'm using and hack it. Thus, I don't really want to redirect those people to a working page they might try to hack.
But is there any other value for example to redirect them all to the homepage? It avoids a 404 which might be seen as better by Google for example, so helpful for SEO. Or would there be a negative, i.e. I'm giving them a page they might try to hack where a 404 page has hardly anything on it so harder to hack (no forms component for example).
