Limit for posting during development and workstation blacklisting


Hello there, we are right now developing a twitter app and It looks like we hit our daily limit of 1000 posts often, and we are also getting a 403 error now from the specific developer machines we were working from, even though they will work with the same account from different machines.

Is there any way to “de blacklist” those specific machines and is there a sandbox mode or an upgrade where we can go over the 1000 limit for a day? Thanks in advance for any pointers.
