You're not old enough or from US to really understand this. But yes, that is NSFW and therefore should be changed.

Not this crap again...

I'm not sure I understand the difference between NSFW and straddling the line.
Can someone post some straddling pics to compare with nsfw pics?

Well, that's where the question of individual opinion comes in. For me, i would interpret this rule rather liberally. I believe the way that bikini provides so little coverage in the OPs avatar would constitute a violation, but something more concealing wouldn't be. Others on the staff may take a harder line.

Or do you mean the kind of "straddling" pics that would also be unsafe for work?

I personally don't have a problem with the OPs avatar, but unfortunately it's now against the rules because everybody went way overboard with that sort of thing.

I'm confused.

Is this SFW?

Hmm, yes. As a Man's nipple's have been considered different than a Woman's.

Making stupid rules like this doesn't exactly help keep members on this website.

This rule shouldn't make someone soooo mad that they would want to leave, that would be kind of sad.

It says pronographic content is never aloud.

Therefore when it says "some suggestive content is allowed" it means something LESS suggestive then porn.
