Before all the updates happened I did around 1x PBN link per day, sometimes 2x per day for blackhat websites which were sure to be penalized anyway and it worked fine for me. Now after the updates some sites are going through a heavy google dance after stop building PBN links. For example I could see google.de is not having such a crazy google dance as google.com. How to avoid this heavy Google dance/sandbox (some sites losing all their rankings -> from 13th to 65th etc.)? Someone figured out the best/most efficient velocity yet? I know it is bad to make a pattern in building links, because its a footprint. I am just asking how many PBN links you guys make and if you see a huge google dance?
