Can you get banned for using addons such as Vendor and AutoLoot?

First off, I have never botted. Yesterday I got a 6 month ban for “botting/automation”. The only difference is that I downloaded the addons Vendor and AutoLoot around when Collector’s Bounty started. Vendor quickly sells equipment for you based on the settings you give it, and AutoLoot loots items much quicker than the in-game auto loot. Can you be banned for using these addons?
