Im almost on board with you on the reports.
I had 2 characters deleted in my time SINCE NG. and one was ibot, one was windbot.
Those two characters were druids who played a huge roll in a war, and they did mass reports at battles, and then eventually banned.
however, people have two choices;
If you dont want to be deleted, don't bot.
If you want to bot and stay on top, bot a shit ton of characters so if you one or two, you got three more to replace them with.
