Problems with upload of File:Super Motherload.jpg
Thanks for uploading File:Super Motherload.jpg. You don't seem to have said where the image came from, who created it, or what the copyright status is. We require this information to verify that the image is legally usable on Wikipedia, and because most image licenses require giving credit to the image's creator.
To add this information, click on this link, then click the "Edit" tab at the top of the page and add the information to the image's description. If you need help, post your question on Wikipedia:Media copyright questions.

Orphaned non-free image File:Opentvlogo.png
Thanks for uploading File:Opentvlogo.png. The image description page currently specifies that the image is non-free and may only be used on Wikipedia under a claim of fair use. However, the image is currently not used in any articles on Wikipedia. If the image was previously in an article, please go to the article and see why it was removed. You may add it back if you think that that will be useful. However, please note that images for which a replacement could be created are not acceptable for use on Wikipedia (see our policy for non-free media).
Please refrain from making unconstructive edits to Wikipedia, as you did at Sex shop. Your edits appear to constitute vandalism and have been reverted or removed. If you would like to experiment, please use the sandbox. Repeated vandalism can result in the loss of editing privileges. Thank you. Philafrenzy (talk) 08:51, 6 June 2016 (UTC)
Not having a user page is not a valid reason to undo a user's edit, as you did on mephedrone. Wikipedia is a public encyclopedia which anyone can edit. The edit you made was not cited and appeared to constitute original research, which is why it was rightfully undone. It was also factually incorrect. Testem (talk) 21:40, 28 June 2017 (UTC)
- @Testem, please refer to http://onlinelibrary.wiley.com/wol1/doi/10.1002/minf.201400024/full and http://infochim.u-strasbg.fr/CS3_2014/Slides/CS3_2014_Willett.pdf for chemical similarity properties.
- DEET and mephedrone are more closely related to each other then Cathine is to mephedrone based on the tanimoto and tversky chemical structuring algorithm. Please use the ChemSpider Structure Search to test the similarity of two different drugs.— Preceding unsigned comment added by Kirill2485 (talk • contribs)
