Just tried connecting using my phone as a wifi hotspot and connected no problem. Seems my IP address has been blocked. What's that all about?

Signed up for the trial of Butter Bot yesterday and got it all set up no problem. It sold all my bitcoins about 7 hours ago and since then it has been giving me a message that the Bitstamp API is experiencing problems. I have removed the extension from Chrome. Now I'm unable to log in to bitstamp.net with the message saying

Is it possible that constant requests from Butter Bot from my IP address has caused them to block my IP address?

Have been in contact with Mahkul about bitcoin for a while. I'll go to the meeting too. Not sure what I can bring to it but I'll go anyway.

2 x Fermi 2050 GPUs

2 x Intel 5520 Quad Core Processors

16 GB RAM

This will cost me £945 a month on a GPU cloud computing plan.  I'm just wondering if it would be worth it.
