It's very safe. You should bot 24/7 this bot is actually allowed by blizzard. As long as you make sure you tell a GM about it it's fine.
Have fun botting friend
Funny story:
My buddy started playing wow, and its the first computer game he ever really played. One day, he gets a tell from someone, telling him to go to this site to buy gold. Well, he goes there, and decides to buy gold. They had a 24 hour promise.
A few days went by, and he had not received his gold yet. So, he decides to contact blizzard. Yup, I said that right, he contacts blizzard. He explains his situation, and the person on the other line in a very confused voice says "You know thats against the terms of service?".
Luckily he had not given them his information yet, and he immediately hung up. I figured this was an entertaing story that kind of falls into this line of thinking. Honestly though, there are new botters that dont quite know how this goes.
If you choose to use the bot, you could be banned. Thats all there is to it. If there was an issue or it was detected, there would be alot more posts in that section....
