I've cleaned up almost all of the 5TDGBRCH4MS037831 stuff as well as some links to irrelevant photos on Flickr.  However, some of the same changesets that included the obvious spam also included other edits that look like they could be either truthful or bogus.  unknown246, did you intentionally make any edits to OpenStreetMap since July 21, or can I assume that all the edits from your account in that time period are from the hacker?  If the latter, then I will revert the rest of the edits.  (I was going to leave them alone, but then I noticed https://osm.org/changeset/169310048, with stream names that look pretty unlikely to be truthful.)  Thanks for your cooperation in getting this mess cleaned up.
