I used to just read your website/forum for the awesome trip reports. Seeing where this conversation is going, I decided to actually sign up, as a user.
Thank you, Viktor, for bringing this up and I hope the paint will be cleaned off promptly.
However, I think it unfair to pin the vandalism on the group of "Russians". You may not be fond of their "speed climbing" but you have no idea whether they painted the wall or not. They did put up the tape, which was taken down, as indicated in the first post.
I personally know some of the "speed climbers" and they are contacting the people who arrived first, to set up the route, to see what the real story was. If they did it, the'll own up to it and clean it up. I, personally, doubt it.
Let's hold off with the assumptions.
