Or it would give him a hint to start contributing. I doubt as many people as you think would just quit, especially if you know them irl.
Let's face it, 98% of clans have their core members, and the rest is filled with people who come and go. Wouldn't it be nice to set new members to initiative status for a few days to have them contribute? Heck, we just recruited someone last night and his donation ratio is 5 to 100 already. The option to stop these people from doing this would be so beneficial to the rest of the clan.
