Seriously.

Anyone who wants to solo Salvage right now is going to. If it means shouting for people to help them to enter and offering them 100k to do so and then D/C during entry, or warp after entry, then that's what they will do. Though with the price drop of alex now, you need to get 40+ per run to cover the price you paid for the 2 people to enter you.

Long story short? You might as well just allow people to enter solo.
