Contributions by User:John2wiki. His latest contribution Payment processor is a copyright infringement, which makes me suspicious about the rest of them. The contributions to Cement kiln and Slag are unsourced and look "too good to be true". Would it be acceptable for me to boldly go and remove them from the articles?

Oh, dear. :/ I agree that it looks concerning. What I would recommend that you do is a three-stage approach. First, I'd leave a note with the contributor telling him that you have concerns, pointing him to WP:C, WP:V and WP:OR. Then I'd put a tag on the talk pages of the articles, {{Cv-unsure}} and open a talk page section noting the history for context and indicating that if the source of the material is not verified, it will be removed as OR & potentially infringement. Then I'd give it a few days. If nothing happens, I'd pull it. Other contributors may be able to find the source of the material, in which case it should be pulled immediately, or may help revise it, if it is verifiable & useful. --Moonriddengirl(talk) 12:40, 7 March 2009 (UTC)
I do have to ask, though, how do you know that https://www.amazines.com/Payment_processor_related.html is not a wikimirror, given the disclaimer at the bottom that "Some pages may contain portions of text relating to certain topics obtained from wikipedia.org under the GNU FDL license"? Wayback is not returning an origin date, so I can't tell. --Moonriddengirl(talk) 12:55, 7 March 2009 (UTC)
It's reasonable; it happens quite often. :) Lacking source for the other material, then, it might be better to simply address the OR concerns and point out that unverified material may be removed. --Moonriddengirl(talk) 14:44, 7 March 2009 (UTC)
The version dated 01:32, January 29, 2009 appears clean. §hepTalk 21:19, 14 March 2009 (UTC)
Y Thanks for checking. :) That version was more clean, but it appears that infringement was actually introduced on 1 April 2008 by an IP contributor. The January 29 version still contained text from that vio, which had been slightly modified and worked in on good faith by other contributors. I'll restore the last clean stub. --Moonriddengirl(talk) 16:55, 15 March 2009 (UTC)
Cleaned. --Moonriddengirl (talk) 12:47, 15 March 2009 (UTC)
