Maybe for generic, crappy shitposts like this:
Indeed it is the risk of a trade, sometimes loss sometimes profit, all you can do is set a target and quickly decide whether you want to take it off or hold it, one day will go up or down without any warning.
More likely for copy pasting. I'm sure a mod will pop in and tell you. No loss to the forum, though. Your posts don't contribute anything that hundreds of shit posters don't write daily, like a tape loop.
Edited to add: Oh yes you're probably right, Joel_Jantsen. I was being too hopeful that a sig spammer would get banned. Should have known better.
