While you may see these reports as spam they aren't quite single-sided affairs like a one off rulebreak that shouldn't necessarily be worthy of a forums report more so the prolonged product of targeting towards Sinz, that said there are such behaviors on Sinz part that do provide staff sufficient means ban him if such things continue. Such as his continued need to inject himself into topics for no reason other than to stir drama, can be seen(for staff) in a recent bug report where his insight was not needed and irrelevant. Or creating reports that aren't concise or clear-cut as can be seen in the report against Doomix
As for this specific report, I don't feel anymore action is needed.
