If I delete an item (for example, a 3D art or a model) Do I loose the viewcount associated with it ?

That is true. You will not lose anything in terms of views (in fact, we encourage you to delete things that you want to delete... you probably do for a reason). However, and I doubt this is what you were thinking, generating illegal views and then deleting an item won't hide it from us; when we review your views at the end of the month, we can still see what it was, where the traffic came from, and will make our determinations from there.

Okay so further to this, suppose you think that one of your items can be improved.

Is it better to delete the item and upload the new improved version as a totally new thing? or to replace the old item with the new improved item?  or to simply upload the new improved version, leaving the old one where it is?

Just wondering what you think...

  As a whole, replace it.  That way, people see it as a new item and KNOW that its "new and improved". 

  There are always exceptions to every rule, such as if the old item tied into another item and/or set, or in a different format, etc.  You get the idea.  Just play it by ear.

Yes, pretty much what I was thinking. Thanks for the confirmation. May as well post a totally new version as you'd have to update the links in forums anyway.  Of course it depends what the reason for the new version was, if there was a fault with the old one, only just recognised, then I'd rather replace the faulty version entirely, but if it's just an improvement, or an adjustment to the tone or a colour adjustment, then the old one isn't really faulty.  Then I'd leave the old one there.

I've already done that with an image of snowy footprints - I left the old one, the original version where the snow was rather greyish in tone, I left it up there, as that's the way it looked on that day, but I also brightened it up a bit and posted that version with the snow looking a bit whiter, both versions are perfectly useable, in fact I've used the original version for a grayer toned image - like on a dull day, or towards evening, and the whiter version for a brighter day, or at least, a brighter scene.
