Yes that was quite clever, did you ever get caught?
Well, yes, sort of. I made the mistake of sending out some of the literature with the return address of my parents, who were still active witnesses. When my father showed up to help with the building of the Kingdom Hall they gave him a hard time. I didn't think that would happen, though the flier I sent wasn't necessarily anonymous. I sent it to an elder I thought might reflect on it, in fact someone whom I had sort of studied with who came into the truth. So I did get caught that way. I was sorry my dad had to bear the brunt of my activism. So that was a lessoned learned.
But I did leave one at the local congregation without owning up to it and heard about it. It worked like a charm. I heard a group of the elders got together and discussed it after finding it. The elders think they are immune to apostate literature and they sort of have to monitor it, maybe even report it to the Society, so they end up reading it. But it pays to know how the congregation works. If you send something to the Kingdom Hall in the mail you need to try to get it into the hands of a ministerial servant. So I used to address the mail to the "Literature Servant". They get requests for literature and other things all the time so it would probably be opened by a ministerial servant, then passed on.
I also sent out letters to ever congregation in the U.S. basically which was on the form of a letter to the GB, sort to telling them that I discovered that Xerxes and Artaxerxes were the same king and how the Bible agreed with that! I was sort of alerting them to the new information and sent a "cc" to all the congregations so they would be alerted to it too. Teee heee heee!!! Of course, they are second party to what the GB was having to deal with. They wouldn't assume the letter was really directed to them. It looked official, since I wasn't doing it behind the WTS' back and it was written as a "helpful" research article for their benefit. That's how it was set up, but actually it meant that 1914 had to be revised. I'm sure after all the elders read it and thought about it for a while, they realized it was a cleverly disguised apostate letter.
One of my favroite fliers was very clever, with some graphics. It basically addressed "Who were the 3rd, 6th and 9th-hour workers?" since they got the penny too like the 11th-hour workers, which are the workers the WTS identified with!! Proof they are clueless about that parable since ALL the workers get the penny so if only JWs are going to heaven and they are the 11th hour workers, then who are the others?
But to no avail. The WTS knows the truth, knows the scriptures and deliberately refuse to change their doctrines in line with the Bible and even go out of their way to deceive. So they are truly the beast that looks like a lamb to the gullible followers but it speaks like a dragon. The WTS is the lamb-dragon/false prophet beast spoken of in Revelation. The 666-Beast represents trinity-believing Christendom (666=three numbers but one number = three gods but one god, etc.)
