I see 3 violations right off the bat:
If you do not wish/like to use PAYPAL, you must ask for other payment method that I will accept. See post #5 for specific policy.
INSURANCE: $2 US extra. Sellers can no longer ask the buyer to pay for insurance. Sellers may include the cost as part of their shipping/handling charge, but it cannot be a separate charge. Went into effect last month, I'll have to look up the specific link.
Not responsible for lost or damaged package with no insurance. Went into effect same time as the optional insurance policy.
They may also have ended your listings because of your wording about buyers leaving less than 5 DSRs. There's a clause (also in policy referenced above) about negative wording, but I don't remember the details. This one is just a guess, though, I think your DSR info is fine but eBay may have interpreted it as a rant.
