I saw the report about master_toledo, is it sure that the other nick belonged to him? (did they have the same IP?) Even if it was him, I think he didn't deserve an immediate ban, only some warning.
Brociu was not punished. He has no one record in penalty log.
Sonic101 was banned for active participance in a group for indirect PR of photos by method of initial like-boosting to take advantages in promotion his photos to POTD, while photos from other users loose any chances for this promotion. This fraudulent game looks like using doping in sports that allows achieve higher results unfairly. Earlier, Sonic101 was caught in use of multiple registration for the same purpose - for liking photos from his clone accounts. Master_Toledo_915 was banned for the same.
Two organizers of that group (Volvo_XC90 and Александр005) have maximal penalty of 45 day ban, while HuronMati was just warned for participation, without ban, because he was caught only in the first time.
P.S. Penalty for Master_Toledo_915 revised: ban time decreased to 7 days.
Thanks for the explanation.

I suspected the same, sometimes they got several likes even on bad quality photos. Actually, there was someone else too, who earned many "photos of the day" with always the same nicks voting, usually on average, not special cars and plates. (Looks like he stopped doing it, but was never banned...)
Is it possible to make a fair alternative to this cheating, where everybody benefits? (For example, subscribing to other nicks) Sometimes the "Popular" photos and POTD only depend on luck, as which photo spent the most time at the "top", and that isn't perfect either.
