Mux,
Renter walkingglitch has rented and cancelled rigs after not paying multiple times on my rigs on 2 different accounts.
Check his activity and plz block him
Also yesterday, there was sudden demand for n-scrypt and when my rig became available, walkingglitch  rented it , blocked it for 30 minutes and then cancelled rent. By that time rent had reduced 4 time son n-scrypt. This is either rig owner blocking other rig or customer blocking rig and waiting if another cheaper rig becomes available. Untill u get wallet for site, Rig owners will keep getting frustrated.
