So what? No one in Russia will start drawing gay-putins, of the fear being subject to compulsory psychiatric treatment. And no one outside Russia is going to draw it because they don't care.
GIS for "gay Putin" suggest that plenty have already been drawn, and not all of them seem to be likely Russian in origin.
I kind of suspect that will continue, if not accelerate.
TBH, so far I haven't seen a single instance of this picture shared after it became illegal.
