Posting three threads seems like an insignificant amount of run around considering it keeps spam to a minimum. It might take a maximum of 2 minutes. The other 48,000 members of this Forum were able to overcome this horrible obstacle and can now freely post without being distracted by spam.
You probably should take a class in politeness and think again about criticizing a service that is offered for free by others.
Oh, except for that, welcome to the Forum.
