I actually own 3 different autosubmitters - bought them so I could reverse engineer them and get code to block them - and you'd be surprised what a little coding can tell you about submitters
Yes there are some LLs that allow them unknowingly - and I allow the form fillers for my partners - but I can guarantee that the auto-submitters go directly to the blacklist and that will be shared with the other LL owners in the very near future
I know we wont agree on the recip links - but then - it really doesnt matter as I know who ranks for what in google
