I have seen quite a lot of declassified KGB documents that have been reproduced in various books, and the handwriting in many of the documents is quite poor, so your first point should be rejected as without basis. As to why he would put up posters, the obvious answer is that he hopes to reach a large audience. Coded ads in newspapers is for people who wish to communicate with others who know the code, such as intelligence operatives. I don't think he s interested in taking calls from or arranging meetings with those he is accusing. In short, your post was silly.
