Title pretty much says it all.
1. Hate when legit threads get spammed, causes too much hassle to get them reinstated.
If it's a dupe or needs removing for any other reason, and it's already hot, then it can be reported to a mod.
Should have a simple block on deals getting spammed that are already hot, seeing as IMO the "spam" button should really only be used to remove the viagra or referral spammers.
Using it for other purposes just leads to misunderstandings and anger.
2. Can we have the duplicate button already please?
Pretty sure this was agreed to be implemented previously...
it'd be a simple button next to spam/expire that'd work in the same way, and when a thread is removed for being a dupe the OP could receive an auto PM letting them know what's happened.
I could list a dozen reasons again why it's a great idea, but i doubt it'll get put in anyway so i won't bother.
