I wasn’t the one who took the post down, but you might want to read these parts of the above posted trade rules:
don’t create a lines account just to sell items. we don’t encourage linkdumping, in which sellers join several different forums/social media only to crosspost the same list in throwaway threads once they’ve gained access to the buy/sell area. it’s spam, and such posts from first-time members will be deleted. lines’ primary focus is not commerce.
and
don’t post overt or private offers to subvert payment mechanisms. we absolutely do not condone breaking terms of service–lying to sneak transactions through without fees. so, do not request “paypal F&F” or similar in threads or PMs. third-party payment processors are well within their rights to suddenly terminate accounts if their users violate their agreed-upon terms, and no one wants that to happen in the middle of a transaction. if you use a 3rd party payment processing service, and it’s valuable to you, include their tiny transaction fee in your item price. this way both buyer and seller have some confidence that their transaction is protected and covered.
Your post was conflicting with both these rules.
Also, if you have a problem with it, please send a message to the moderators instead of posting a public complaint, which will not get you anywhere.
This said, you will get contacted soon to sort out the issue.
