It seems to me that this posited range-block is not going to work - if we look at users (with non-blank user pages) beginning with 70.105 there are only 6, one is already a suspected sock of PW and several are manifestly not PW-clones. So can you just please block the IPs + WestfieldIns which I brought to your attention (quite a few edits ago) and put a stop to the incessant quacking? (I did have a look at range-blocking. I can see why you view it with some circumspection.)
