On 1 August 2005 I decided to contribute an article from my wiki http://www.jnanabase.org in Wikipedia. My wiki is GFDL, just like Wikipedia.
I proceeded and copied the text from my wiki's article and I pasted it to a new Wikipedia article [[Sphaera Mundi]]: http://en.wikipedia.org/wiki/Sphaera_Mundi
Because the article was written in my wiki (which has 1834 pages), I added a standard attribution notice to cite the source, with a link back to my wiki's original article, as per required by GFDL and Wikipedia's policy: http://en.wikipedia.org/wiki/Wikipedia:Cite_sources
On 3 August 2005 another Wikipedia user edited the article and added categories. On 9 August 2005 a different user cleaned it up and disambiguated some links.
On 12 August 2005, [[User:UninvitedCompany]], who is a sysop, removed the attribution notice.
On 14 August 2005, [[User:Joe Kress]] (I don't know that user) re-added the attribution notice, as Wikipedia's policy requires: http://en.wikipedia.org/wiki/Wikipedia:Cite_sources
2 hours later UninvitedCompany removed the notice again. 3 hours later I added again the notice.
We had some discussion with UninvitedCompany and he says the source of [[Sphaera Mundi]]'s shouldn't be included in the article because it's an "unreliable source" and because it's "spam", although my wiki appears in the 3rd position in a Google search for "sphaera mundi" and most other pages of my website have a PageRank of 6, while the site has been slashdotted 4 times: http://portal.wikinerds.org/taxonomy/term/49
According to the GFDL licence and copyright laws, proper attribution must be provided. Citing where an article was copied from is not spam.
In a similar incident, I also copied an article from my wiki to a new Wikipedia article with title [[Erhard Ratdolt]], with an attribution notice. When UninvitedCompany removed the attribution notice, another sysop deleted the article saying "copyvio of Wikinerds. Deleting." - and this shows that an article copied from an external GFDL source into Wikipedia without proper attribution is copyright violation and a violation of the GFDL licence.
If the notice is deleted again from [[Sphaera Mundi]] (or any other article from my wiki without proper attribution), I will request its deletion.
This sysop also removed other attribution notices and various other edits I have made, so I believe he is bullying me. I have requested mediation and I have collected all evidence at http://en.wikipedia.org/wiki/User:Www.wikinerds.org/Bullying
Please someone explain to this sysop that articles copied from external GFDL wikis must contain proper attribution. We don't want our articles to appear in Wikipedia without attribution of the source. If you don't want to include the attribution link, please delete articles copied from Wikinerds.
