They are obviously posting this so they can close the pair without making good on it and hope it will not effect the volume on their other pairs. They are just trying to prolong their scam exchange and steal what xmr they can, i don't doubt they stole it themselfs.
If anyone is displease with how Livecoin is handling the vulnerability exploited of XMR, and believe they are scammers, Please support this flag against them.

This particular flag was raised by a user who experienced loss due to Livecoin's handling of the Mona 51% attack. However, the thread mentioned also discusses thier handling of the Monero matter.
Thanks Bones, I have been to busy to keep up around here and meant to get back into that Livecoin scammer thread but I don't get paid and have to balance my time wiser these days.
