== reversion or redaction of unsourced material == 

 I see you are an enthusiastic new editor on English wikipedia.  I note from your edit log, that most of your edits are reversions to previous versions of the page, mostly for unsourced content reasons.  Unfortunately, this may result in loss of valid content 
 from the encyclopedia, which may be able to be sourced by an industrious editor.  I would suggest that most such content you've deleted is in fact, accurate.  Unsourced material may be challenged and deleted.  However, I don't see any such challenges prior to your deletions/reversions.  Usually, challenges to unsourced material result from the material being suspect, i.e. unable to be verified because it is false or speculative, or editorial rather than factual.  A better procedure in these cases is to add an inline or global maintenance template to the article like 'citation required'.  As much as half the encyclopedia is unsourced or 
 inadequately sourced, so a conservative approach to redactions is warranted.  Your time would be very well spent, researching and citing the material you're concerned about, rather than redacting it.
