Yeah they absolutely deserve it if they did in fact say "give us $300 and we'll remove/hide the neg feedback/review". Ripoff Report does the same shit. Its not worth the small amount of cash in exchange for the amount of damage you potentially make your brand and resource subject to. Either you sell advertising or you don't.
As for the recent investment debacle, I don't think they are pompous for rejecting offers from Google or Microsoft, even if they are hyper inflated ones. Seems most traffic behemoths of the internets are getting hyper inflated valuations. Kinda like a dotbomb buildup 2.0. They may be foolish to reject it with the current view on their business and standings, but who knows, maybe in the future they'll pull a Facebook and get a valuation of $15 billion that everyone thought was impossible to achieve when Yahoo offered them $1B or so for the whole company a year before. They, after all, ended up taking a $240M investment from Microsoft for only a 1.6% stake. Look at that incredibly annoying and useless time wasting site we call Twitter, getting a $100M round of funding. Or YouTube and Google buying it for over $1B. Unreal is all I have to say when news like this drops, rejected or accepted, its all just unreal.
