IMO documenting your work and crediting content creators is generally a good thing. While some sites like Renderosity  have a fairly relaxed attitude about it , others are obviously more hard-lined. I personally think that is a mistake but they obviously have their own philosophies and agendas. I would note that the Deviant Art example you linked to relates to a group within that site - I have no idea since I don't frequent it whether the parent site is so scrutinising.
It might seem heavy handed, and I don't know all the details of that case, but rules are rules if you play the game on a given site or in a group - 'When in Rome' and all that. If something has been misunderstood or misinterpreted by the admins or users then that's worth clearing up, otherwise accept the flack.

From my point of view even if an artist doesn't include credits where the render is posted, so long as they are prepared to do so when asked and don't dishonestly pass off other people's skilled work as their own, I don't see the problem. Proactively crediting is useful but not always practical (if a lot of ready-made elements are used and time is limited). A lot of people hold to the opinion that since they payed for an item they shouldn't have to credit ('why should we have to do their advertising for them?' - well, if they make good stuff and we want to see more...), but I do think it's at least fair when someone enquires.

There are often times when browsing the galleries here when I wish there was slightly more info posted with renders giving specific details of third party content, software actually used to render, whether postwork was involved etc (but this is another long running debate). I can't complain as I don't always include those details myself.
For me though this isn't a question of attempting to qualify the competence of the artist based on what they actually did in every minute detail. For me if it's an interesting image, composed competently but more importantly that it resonates something beyond the sum of it's elements, then I can accept the artists input. That has value to me.

In the Poser and Daz hobbyist domain it might seem particularly relevant to credit all the elements used in renders since for the most part we don't make all our own items - although we may tinker, adjust and refine what we buy or pick up as freebies. But generally we don't - it's not the game we're playing. We're collaging, composing, concentrating on the ideas, or just simply having fun.

Serious or fun, ther results can still be art - don't let anyone tell you otherwise. If a group or site doesn't like how you do things, either see it their way or find somewhere else to play.
