Yes, that's common. I still get those occasionally and I hate them the most
because you must hover over the URL and sometimes follow to judge before
deletion. No purging = asking for more.

It's a brute force typa' thing. Same with rel="nofollow". Likelihood is
enough to make financial incentives prevail.

Not hard if the spammer comes to realise that it's close, but no cigar. By

Whatever you do, make it hard for entry procedures to become scriptable or
for the process to be transparent. Intercept this early on, before releasing
code. There's a snag here: the harder a script becomes to write, the harder
it becomes for the genuine user to contribute. Corollary: spam deters real
contributions. If only the script kiddies had less spare time in their
Obscurity is often the only way to guarantee that automatic (as opposed to
manually-entered) spamming can be prevented. I continue to suffer from spam
