Yes, because its a considerate move to make for people who may not appreciate seeing vulgar words.

Yes, because I don't swear in real life, so why do it here?

Maybe, but it depends on where you're swearing. If it's on a Deviation it's ok because art is a form of expression, but if it's in a comment to someone, you should be careful what you say.

It's only ok if you're really mad; it shows you anger.

No. I swear in real life, so why censor myself here?

No. If people are too sensitive to be able to handle swear words, then perhaps they're too young or immature to be on dA.

I'm indifferent on this matter. I don't care if people swear, but I think think they really shouldn't.

Some swearing or cursing is ok, but too much of it makes a person sound like an immature idiot.

None of the above fits my general opinion on the matter. (Comment if you wish to express your opinion in your own words).
