Just some of the issues when there are replies to spam posts (or embedded spam posts)
Threads tend to meander and go off topic. Removing a thread started by a spammer then removes these other posts and some users get peeved.
Picking and choosing which posts to remove from a thread can be a begger and a time waster. And clicking the wrong "X" is likely to have some irate user breathing down a mods neck - and the spam still stands.
So it can add a little extra work and angst.
Netmaestro is right in my (not so) humble opinion.
Please don't respond to spammers.
Thanks!
