This account (now deleted) is always posting the same message that links to a different documented API function each time. The dead giveaway is the Google Ads heading and large Web development services banner in addition to the consistency of every answer that contains no helpful information except a direct link to the advertisement page.
I noticed the account when the message was wrongly posted as an answer to a C# Winforms question. I flagged the answer for a moderator attention; however there seems to be no way to flag the entire account for moderator attention so I'm posting the info here.
For my justification of flagging this account see May I promote products or websites I am affiliated with here? in the FAQ.
Update 1 - further investigation
Here's a sample of the URL that was posted (from my browser history):
Here's a sample of the answer format - it's always the same: one sentence, one link, linking to a function on the java.pakcarid.com domain.

These answers are relatively useless as far as information considering they are templated and especially compared to real answers in the thread.
Update 2 - Report this Adsense account to Google
I'd encourage the community (if they feel comfortable) to visit http://java.pakcarid.com/ click the "Ads by Google" logo and report the account. I submitted the following report to Google. Feel free to use it for your own report.
This site creates user accounts on https://stackoverflow.com/ and plants templated, useless answers that link to its Google adsense pages. See discussion about it here within the community among users and moderators spam account/domain needs attention - target java.pakcarid.com
