It certainly does. I've had both the polyfill that comes in 510 carts and PTB melt and singe, and I've had all four 510 attys I've owned get that "burnt dog hair" taste in less than a month from burning the wick.
As far as I'm concerned the burning wick issue is resolved.
No, it does not burn in the 510 atomizer.
As far as the filler material goes, I have NEVER had any filler material burn, singe, melt, or anything else using my 510 atomizers. I have used the standard polyfill and the blue foam. I have also never seen anyone, whom I believe knows what they are doing, claim that they had any filler material burn. In other words, I don't believe it.
I believe there are many people who THINK they have had the polyfill melt and stick to their atomizer, and I believe these people are simply twisting their cartridges and getting the filler material snagged on the bridge and they just THINK it melted and stuck to it.
But since there might be credible claims (other than yours) of filler material burning, melting, or singeing under normal operation with a 510 atomizer that I may have missed, I have "asked the experts" to see what they have to say.
Here is the thread:

So it remains my contention that the 510 atomizer will not burn, melt, or singe filler material under normal operation. And until the same can be said for cartomizers, I would not recommend them to new users.
Of course, for me personally, I only use them if I absolutely must.
Filler material of any kind detracts from the flavor as far as I'm concerned.
