Are you sure this “SV1” blocking wouldn’t block regular users actually visiting the search result they found?

I just checked my logs, finding a *lot* of these SV1 accesses, and most really just get the page and all script files referenced in it (so they certainly are from this Linkscanner), but some actually get all images, too, just like for actual human users, and some of these have the exact(!) UA string that’d be blocked, without any “.NET…”. So, well, I’m worried I’d block real visitors (who just happen to have this Linkscanner installed) this way, too…
