Hey!  This changeset appears to consist mostly if not completely of spam, similar to the spam we previously saw from unknown246's account (discussion on https://www.openstreetmap.org/changeset/169357242).  For now, I've gone ahead and reverted the whole thing in https://www.openstreetmap.org/changeset/169829340 .

What happened?  Was your account hacked too?  If you are intentionally creating new accounts in order to continue spamming, I'll have to ask what tools the Data Working Group has available to stop this.  If you believe some of your edits to elements are valid, please explain which ones and where you got the data (your changeset has an unhelpful description and no source) and we can reinstate those edits.

Thanks for your cooperation.
