Just means the market needs to raise the prices. In bitcoin this is similar to raising transaction fees to add a disincentive for DDOS attacks. Right now, it seems ethereum is just an almost-free VPS service and people are surprised that actors are taking advantage of it.

Similarly, Ethereum has a gas limit per transaction.
