Not as simple as it needs to be. Requires textfile editing to make it work.
Also Q has secured non-windows device(s), may be impractical to even do this and while some autists may verify others may be confused by shills who "prove" it doesn't work by editing the textfile wrong etc. Visible tripcode is visible to everyone.
There needs to be a "board salt-free" super secret tripcode. Q wouldn't want to lock his identity down to CBTS or any one place.
