All I understand is some bad neighbourhood bad links such as from those adult sites, spam sites, scam sites etc that link to my site will not beneficial me, but how do I tell google or other search engine to remove or ignore such links?
Unfortunately there's no such thing, unless you can get the site owners to remove these links, search engines will see them
Yes, you can tell Google to remove, but first try to contact the webmaster to remove the url and still there is no response from them then report your issue through this link http://support.google.com/webmasters/bin/answer.py?hl=en&answer=1663688 . Choose appropriately. I hope this helps you.
