orders on both sides is perfectly normal market making. Spoofing is an order that you want at the tightest level, then a bunch of orders that you don't, on the other side, at levels further back than the tightest level to inflate the volume in total. Buy at level 1, sells at levels 3,4 & 5 where you never had any intention of selling. It's a problematic defintion, and enforcement etc. I don't claim to be an expert on this, fwiw having never spoofed an order and not being a trader.
