Lmall is big cheater, cancelled many of my orders a week ago

This LMall is fishy. This is the first time i've heard of it, but just now i try to register, it says my email has been used. Tried a few emails still the same. Then i try login using these emails and the password that i commonly used and hooray successfully login. Thing is that particular password is only used for my lazada, 11street, shopee, shoppu, and lelong accounts. So this LMall must have stolen my infos from one of these portals. I'll steer clear from such a marketplace.
