Can you cite examples? Where I see this, it is usually because the user did not post a log as a code block, e.g. they did something like:
log line 1 blah blah http://example.com/foo/bar
log line 2 blah blah http://example.com/foo2/bar2
log line 2 blah blah http://example.com/foo3/bar3
instead of
log line 1 blah blah http://example.com/foo/bar
log line 2 blah blah http://example.com/foo2/bar2
log line 2 blah blah http://example.com/foo3/bar3
but I'll check to make sure the URL check does in fact ignore URLs in code blocks.
