Please stop link spamming articles related to root finding. It's against policy, several people have reverted you and explained why in their change messages. If you keep this up, you're likely to get banned. Martijn Meijering (talk) 14:57, 29 December 2012 (UTC)[reply]

I am tryong to understand why this is a spam. I have paid attention to every one of their messages and altered my content accordingly - out of curiosity have you read the content of my edits? If so, can you please explain why it is a spam, I would be glad to fix it. The material I have posted there is absolutely in line with the other contributions in that section. Thanks.

This is your only warning; if you insert a spam link to Wikipedia again, you may be blocked from editing without further notice. Persistent spammers may have their websites blacklisted, preventing anyone from linking to them from all Wikimedia sites as well as potentially being penalized by search engines.
