I have removed my negative tag and support since LTC Casino already started to pay the winning, of course if thing goes wrong I would give negative tag again and wouldn't remove it ASAP until I see a good indication to remove the tag, this may take few months until I don't see they have no intention to scam.
But I'd say @Pmalek's decision isn't wrong too, each people have different view to consider removing the tag. At least he's not a kind of user who wouldn't remove his tag even though the accusation already resolved.
