 :Hi Mark. Not deleted as such, but your addition of the Jim Rose Circus as a tour act in the Pearl Jam article has been removed by . I'd guess that it's because you haven't cited a source for the information. The best thing to do at this point would be to ask Lugnuts why he thinks the information isn't appropriate (and explain why you think that it is); you can do so by leaving a message either at  or the article's talkpage. 
 :One thing you definitely shouldn't do is reflexively re-add the material, at least until you have a source to support it. Repeatedly adding (or removing) the same text in an article is called edit-warring, and is strongly frowned upon - doing so more than three times in a row is likely to get you automatically blocked. Talk to Lugnuts about it, and if you need any help, feel free to  directly.  ‍ "
