Logically, no one who is going to ignore someone will do this, but:
Imagine that I have a user being "followed" by the bot. And later I "ignore" the user on the forum, what will the bot do? Or I "ignore" a user on the forum, and then it comes to the bot and I request to "follow" that user, how does the bot react?
The only "ignoring" that matters is the bot's in-house ignore list.
So, if I ignore a user on the forum, and they quote me, will I still be notified? It makes sense.
I believe that whoever joins the forum will end up not ignoring the Bot.
TryNinja, it would be fun to present some Bot statistics. Number of topics followed, users followed, users ignored, most followed words, most followed topics, etc.
Or do you happen to not have this data, or do you not want to share it?
