I really don't understand why people on this forum need to be so unfriendly. Nobody is forcing you to sign the petition, so just ignore posts that don't interest you or that you don't agree with.
I applied for a Schengen visa last year and specifically applied for a 6 month visa, not because I wanted to spend 6 months in Europe, but because I could then visit the area more than once during that period without having to go through the drama of booking an appointment, going down to London (I don't live in the South East) and paying for the visa each time. Not all people who apply for longer visas are doing so because they want to 'disappear'.
My understanding is that the bond will also not be for specific people, it will be for people from specific countries. So if a few people from a particular country overstay, then bonds will be introduced for visitors from that country who cannot show sufficient funds or accommodation or whatever rule they want to make up in the future. Correct me if I am wrong, but I do think that this will affect more than just a few people.
