<p dir="auto">Well, that's the crux of the issue. We couldn't even deny newlines, as there's already one user with \r\n in the name: <a href="https://www.openstreetmap.org/user/Mohamedkaizen%0D%0AMohamedkaizen" rel="nofollow">https://www.openstreetmap.org/user/Mohamedkaizen%0D%0AMohamedkaizen</a></p>
<p dir="auto">I think the way to reduce this risk as much as possible is to use a different delimitation character that is more commonly related to URLs than casual text. Right now, the longest name of a contributor is <a href="https://www.openstreetmap.org/user/bwdlqwbdjlbqlwdjbqlwjdbqljwbdlqwjbdlqwjdblqjwbdlqjwdbqlwjdblqwdblqjbdlqjwbdljqbwdljqwbdlqbwdbqwdblqwdlqwbdlbdlqbwldbqlwbdlqbwdlqbdlqbdljwbdlqwbdwlbqlwdblqwbdjlqwbdjlqwbdljqwbdljqbwdljqbdlqwbdlqbdljqbdljqbwdljbqldbqlwdbljqwbdljqwdbqlwdbqlwjdbqlwdbqlw" rel="nofollow">bwdlqwbdjlbqlwdjbqlwjdbqljwbdlqwjbdlqwjdblqjwbdlqjwdbqlwjdblqwdblqjbdlqjwbdljqbwdljqwbdlqbwdbqwdblqwdlqwbdlbdlqbwldbqlwbdlqbwdlqbdlqbdljwbdlqwbdwlbqlwdblqwbdjlqwbdjlqwbdljqwbdljqbwdljqbdlqwbdlqbdljqbdljqbwdljbqldbqlwdbljqwbdljqwdbqlwdbqlwjdbqlwdbqlw</a> at 249 chars, so none of these suggestions would be inclusive.</p>
<p dir="auto">And database validation is probably too much of a slowdown for how often this library is called.</p>
