It could be the case that your address was included in the sequencer blacklist (participants that were picked by the sequencer and didn't contribute in time due to any reason (I suppose it could be a network connection or a frontend bug)). That way we prevent spam attacks.

@rkr021 your address have been removed. Please consider:

1. Your upload time should be at least 30Mbps

2. You need to pay attention from time to time to your browser (if it goes to sleep mode when the sequencer choose you you could lose your chance)

3. You can use another client implementations to avoid worrying about these constrains

4. We are not offering any kinds of airdrops nor economic incentives. Your participation allows you to contribute into scaling Ethereum through sharding. We will deliver POAPs afterwards but they are just a recognition item (do not have value).

We apologize for the inconveniences but the blacklist allows us to protect against bot attacks (even though bots have found clever ways to avoid it and right now the lobby is super packed with them). We are discussing the possibility to reopen the general contributions after the special contributions period. So if you don't get a chance until March 13th, you could try it later.
