Question is, how often newbies create such a quality content that them posting images cause huge inconvenience on mass scale?
The answer to that probably is never.
If a newbie wants to promote a legit service and needs to post images for that, they will simply buy a copper membership.
But newbies who don't want to buy one, most likely don't post quality content which requires the ability to post images.
Ranking up isn't that hard if you aren't just spamming.
