Now it seems like there has been lot of down vote lately for my answers. So Workplace won't allow me to add any more answers to questions.

You can delete your account if you want, but if you're interested in participating here, it would be better to tackle the problem that's causing you to be blocked right now. If you improve some of your downvoted posts so that they can be upvoted instead, the block will go away. The block isn't meant to be punitive; it's there to keep people from flooding sites with low-quality posts. We're not trying to make you go away; we're trying to put a temporary stop in place so that you can make improvements and then continue participating.

Many of them will receive upvotes and be better received.
Hope this helps!
