They said call and register your displeasure. That's far from harassment.
>The LGBT rights group is calling on New York City comptroller Scott Stringer, and New York state comptroller Thomas DiNapoli, to contact Usmanov and Tavrin, and demand that content depicting, promoting or extolling the abduction of gays, blacks, Jews and others be taken down from VK.com, and that all accounts associated with such materials be deleted.
You're doing yourself no favors by taking liberties with what was said instead of directly quoting the article.
But the sentence you quoted says no such thing, it says that the group itself is "calling on" (which is not the same as "calling") the comptrollers to do something. The group is not advocating that anyone else call them.
