Because comments are a bit of a status symbol and are more visible to visitors than being on someone's fave list. Plus, it is an ego boost for someone to get positive comments about their work.
No, there is not a limit to how many favourites you can have on deviantART. You can have anywhere from 1 to 5,000 and more. Putting a limit on favourites would not be ideal for dA, because favourites are a way for artists to see if people like their art and to get exposure.
You can make a plz account the same way you make a regular account on deviantArt. People who have plz accounts never talk or post deviations, they just make it for fun and let people on deviantArt use it in their comments.
No, you can't do something like that.
An OC on deviantart is short for Original Character. Like for your own stories or from tv shows, cartoons or anime.
Most people like fruit, however it is a matter of opinion. People have their favorites and also ones they don't like.
I suppose that all normal people like Carpathians from Romania.
Check sites like Youtube or Deviantart.
When people type in caps like "THIS" is usually means they're "yelling."
If you are asking whether you have to create the artwork for the prints yourself, then yes, you do. If you are asking whether you have to get the artwork printed yourself, and then sell them through DeviantART (like you would on ebay), then no - DeviantART does all the printing itself. All you have to do is create the artwork, submit it to your profile and then submit it as a print. Whenever someone orders a print, you get the payment and DeviantART does the printing and the sending.
On Fanfiction.net, deviantART, places like those. There aren't that many.
No, Radiar-Sonic art is nothing like Puritylf4.....
Yes, you can have as many accounts as you would like.
