I don't even have Best Offer turned on when I list an item yet I still get lowball offers from time to time. I also block anyone who I think will be trouble. A few weeks ago someone offered me half the price of what I had the item listed for, telling me I will never sell it at that price (despite another seller selling the same item for $5 more than my price a few days before that), so I told them forget it and of someone else bought it 3 days later.
If I wanted to take offers, I'd have Best Offer as an option.
Not related to that but what about people who can't read a description. I'll have a game listing that says "this item is the original version, not the greatest hits version" and then I'll get a message from someone asking if it is the greatest hits version or not. I usually ignore and block those people as well since if they can't read a short description, they are not someone I want to deal with.
Then there are the people who use buy it now, then message me with a question about the item after they bought and paid for the item. Also the people who wait until the last minute to buy a gift and expect it to be delivered it a day or two.
Here's an example of what the type of person I don't want to deal with (actual messages):
"Will you sell it for $10? Ill buy it now."
Then another message from them:
"In case that item is DOA or not working properly, do you refund payment or replace the item?"
