You're right, nobody should have to pay for protection but unfortunately that's the world we live in now *sigh.
I don't see any reason why you should take Paypal if you don't want to...that's entirely up to you. To tell the truth, I applaud you for trying to keep it fun. (Which is getting harder & harder every day)

Just keep on doing what you're doing, we already know the searches are being manipulated and we can't do anything about it. Just be glad you're not a NEW seller...they're REQUIRED to accept Paypal.
