The hope is that others will read it and be able to take away something of value. For every few users that post something malicious, there is someone reading/posting that is genuinely ignorant and looking to get involved with the community with good intentions.
If just one person thinks to themselves "I'll read the stickies", then I consider that a success; whether it is the scammer, the ignorant newbie, someone foolishly considering to fund the loan or just a passer-by that doesn't consider such things as their forum time has become habituated in an unfortunate manner.
I'm sure most of my "tips" go unnoticed, but I know of at least a handful of people that are more better off because of it. To us, it seems like systematically beating a dead-horse, but to those just entering the forum this may be the first time they hear of such things; elementary as they may be.
just posting a "drive by" loan request hoping some newbie will fall for it. They will probably never read your message. :/
It's for the newbie that may fall for it, more than anybody.
