Volunteering as Punishment

The other week I saw this post about an 11 your old girl who is being required to do six hours of "volunteer work" to get her free Oyster card back or else face a ban of one year.

There has been a lot of discussion around the increase in the use of community service.

Should something be referred to as volunteering if it's not entirely voluntary?

Apparently those that volunteer (especially at an early age) really enjoy it and go on to volunteer more as they go through life. Some agree with this "ends justifies the means" argument. Others don't.

What do you think? Is it OK to use the word volunteering when referring to punishment through community service?
