It's probably worth putting a scam warning if you are going to link to those sites. Anyone who types their private key in to one of those sites to "see which page it is on" or to "see if it is in their database" or to "sign up for monitoring/alerts" or whatever other nonsense they try to sell you will have all their coins stolen. Many newbies will not understand this.

Ok, so either tell us what the vulnerability is so we can patch it, or go off and make yourself a millionaire. We know you won't do either.
