I've just noted that the user @lomber which kindly just today supported the OP here
math.meta.stackexchange.com/q/28331/505767 was suspended for voting irregularities. I'm not aware about the rule for suspension in case of voting irregularities, is possible that the suspension is related to the opened support give to the aftermentioned OP? I mean to ask if this kind of support can be considered an infragement of some existing voting rules or if the fact is completely unrelated. Thanks
