Ignore list already full. Spoiler: of spam bots

After daily ignoring spam bots I noticed the message appearing "Unable to ignore xxxx".
I don't know how to remove all so I can start the odyssey again.
And since Blizzard doesn't care about bots that gives them profit, I don't feel like this will be over.

Is there a way to NOT join "Trade" channel when I log with a different char?
I hate to type /channel leave Trade every time I join a game.. zzz

You can clear your block list but it doesn't work in game. Have to go to your block list on battle.net app. I cleared mine and went back to blocking spambots, my block list will probably be full again in a few days and only because I'm barely playing any more these days.

Meanwhile at blizzard

Something I've always wondered is why they generate random coupon codes.

its not a real coupon code, its a way to change up the message so its just slightly different each time and doesn't trigger any type of repeated spam protection.
