I have been coming to Fakku for years (since at around 2010-2011) and to my surprise, did not even remember I had an account on here.
Anyway, the concern I had was actually the lack of announcement to the casual users on here. Before you say anything else, I am aware that there were multiple announcements on the site for months. However, those announcements were more caught on by those who come in regularly rather than those who come here one in a while. Thanks to the Wayback Machine, the last announcement on the homepage was on December 11, 2015. The actual post can be seen here:
Coming Soon. In the middle of that entire post was 2 paragraphs regarding Scanlations. People who read that knew what was coming but for the casual, it was quite long to read. The fact that the announcement was in the middle made it quite easy to skip over in my opinion. Add to the fact that as new content was added, the post would move down until it is no longer the homepage. The casual user could have easily (and by the sound of it did) miss the announcement.
This is just a personal opinion of mine but I think if there was daily notification from that announcement, whether through the headline announcement box like the one now, or even a pop up like the "Are you over 18?" box, there would have been less anger towards the purge. Then again, that is just my opinion.
