In Person Activism

If it doesnt fit into this community, be so kind and point me in the right direction if possible.

So, in case this post fits here:

This situation has gone on for a few days. Recently a ticket machine here in germany got covered in fascist stickers, showing the flag of Nazi-Germany [Flag of Nazi Germany] and propagating Ideals of the "white-power-movement". I believe the picture speaks for itself. The stickers were removed a few days ago, but returned shortly after. (Picture shows second installment) Today I took some time out of my day to remove them, but it was quite a strenous process. Thats why I came here to ask for any ideas concerning the removal, or general thoughts on the situation. I know that it's an uphill battle, since putting new stickers down is a process of seconds, but it also feels terrible to do nothing. Any help is appreciated!
