Well unfortunately banning SHA1 is not as comfortable as banning hosts. But you can build yourself a search file rule like this:

When receiving search results
with 'urn:sha1:ABC...' or 'urn:sha1:XYZ...' as file urns

Choose one of:
ban their source (for 7 days)
delete them
hide them

And enable the rule permanently.

When you find a new SHA1 you need to add it manually.


I know this is not the ideal solution... but its the only think I can offer right now.
To help a little the search table supports row based Copy&Paste by shortcut keys. On Windows CTRL-C. Just copy the line, paste it into some editor and extract the SHA1.

Hope that helps at least a little....
