Hi, user Tajik is systematically searching and changing Turkish related articles with wrong and unsourced informations. WikiArticles are not improving because of his/her wrongly editings. He/She is searching 'turk' or "turkic" words in an article and deleting or deforming sentence or changing with 'persian' word in a baseless way. And he generally makes this secretly. He/She is making these changes with 'minor edits'. 
A check to the minor edit box signifies that only superficial differences exist between the current and previous version: typo corrections, formatting and presentational changes, rearranging of text without modifying content, et cetera. A minor edit is a version that the editor believes requires no review and could never be the subject of a dispute.
By contrast, a major edit is a version that should be reviewed to confirm that it is consensual to all concerned editors. Therefore, any change that affects the meaning of an article is not minor, even if the edit is a single word.
However, Tajik's systematically minor editings hardly affects of articles. And he/she always uses this illegal method. Please have a look at his/her contributions;

http://en.wikipedia.org/w/index.php?title=Hephthalite&action;=history (Almost all of the minor editings by Tajik)

Actually, these are the ones that i could see. Please look at Contr. ;http://en.wikipedia.org/w/index.php?title=Special:Contributions&limit;=500&target;=Tajik
Secondly, if he/she is frustrated in editing he/she is inviting to article other wikipedians. What can be the evidence for teamworking else. He/she is not seeing wikipedia as an culture and information organization. He always deforms sourced turkic related articles and infos. He/she could has problems with other nations and races but is here true platform to solve his/her nation-based problems? Please help to improve Wikipedia...
