I believe currently it's a $1000 non-refundable fee to submit a domain claim, e.g. you believe someone else acquired a domain knowing you owned the copyright, and then try to take it from you without having to buy it from you - whether it is or isn't for sale.

$1000 cost + cost of whatever a bad-unethical lawyer charges to try to steal a domain doesn't cover the costs of time spent of the person you're falsely accusing - regardless if they hired a lawyer to get a proper legal defense - making their unrecoverable costs even higher - a claim submitted with no evidence, stuffed with repeated non-sense garbage that should have automatically been denied.

If I wasn't dealing with other shit then I would have filed a complaint against the lawyer in the European country who initiated the wrongful claim-attack-theft attempt.
