Avoid copying exact text or very close paraphrasing
To avoid copyright infringement, it's necessary for us to right things in our own words. This edit uses too much text from the source. For example, you put, "a self-published newspaper in Donetsk provides the phone number for subscription into the Battalion" and "battalions can be brought under the command of the Ukrainian Interior Ministry, allowing them to operate legally" whereas the source had "A self-published newspaper in Donetsk gives the phone number where "Ukrainian patriots" can sign up for the volunteer battalions" and "their battalions can be brought under the command of the interior ministry, allowing them to operate legally".
The best way to avoid this problem is to read multiple sources, write things in your own words, then back up your facts by using the sources.
Thank you for your care for the quality of Wikipedia. Of course I also want Wikipedia to be the best it can. Unfortunately so much is happening in Ukraine right now (the main subject of my Wikipedia-editing); and my amount of time that I can spend on Wikipedia has decreased.... So sometimes these days I have to compromise.... Better to update the article in not the best way, then not to update it... But I will try not to repeat my mistake you pointed out above! — Yulia Romero • Talk to me! 14:56, 19 August 2014 (UTC)
