Zero Eth Transactions Spamming EOS Crowdsale Contract

![](https://steemitimages.com/DQmU3vqmyYohzgUiWub9Vyz4DagMr8g9o83MgWKbhBM5weo/image.png)

I'm noticing a bunch of 0 Eth transactions spamming the EOS Crowdsale contract.  They all seem to be coming from smart contracts that have already bid into a block.  There's no telling if these are just badly written smart contracts or if there's some intentional effort to spam the EOS crowdsale.  Thus far, the EOS ICO has really slowed down after raising ~$180m in the first days.

There hasn't been any announcements of network congestion yet but it's definitely something to keep an eye on if you're trading Eth or EOS.  The contract can be viewed here:  https://etherscan.io/address/0xd0a6e6c54dbc68db5db3a091b171a77407ff7ccf

**EDIT:** As @altruist have mentioned in comments, many of these are transactional aspects of EOS at work.  That explains things quite a bit!

Most of these transactions are not spam, they are issuing a claimall function to the contract to claim your share(s) of EOS token(s) you have transferred ETH for. 

TLDR/Short explanation: When an user clicks the "Get EOS Tokens" button, it will try to send one of these transactions for '0 ETH.' 

If you click one of the transaction hashes, you will see this at the bottom:

I might have to buy more on the slow down.
