But is it really stealing if you are making a nice profit, and they are getting more fp then they would on a swap thread or other method they are using? Often with a big Arc, someone can get a great snipe, but the owner still gets 1.8 or better. If the person is self leveling, any free fp is a bonus for them. If not, they should learn to prep their buildings properly so snipes below the percent they want to receive don't happen.
I recently got "sniped" on one of my buildings at 1.95 when I was prepping for 1.93. Was I mad? Heck no.
