who proposed this thing has also an idea about how to realize it?

If the point is ensure that Tor ip could have access, it means give to a bunch of potentially dangerous ip addresses a priority.

If the point is use a blacklist ip based or not, it requires an alternative.

Another example is wiki. The same blacklist protects also wiki and bugs since there is no other plugin that we can use to stop spam there.
What do you suggest to apply there?
