That's a lot of tokens, I feel sorry for you. Your only hope is for the dev to comeback and reward your stuck funds. Worse scenario, the dev have already dumped all the tokens accumulated on the lending platform.
Well, I'm not sure though cause as you can see here https://etherscan.io/token/0xee609fe292128cad03b786dbb9bc2634ccdbe7fc?a=0xebc3b544293e1e61ff20dfeefc15929bb18443a6 - this still contains 100k of postokens and I think that's the development reserve which is still untouched.
