Very easy to get rid of Tobias.
When there is a drop off in box office numbers, he'll be the first one to show up, putting down the numbers and MOS in the process.
He'll then post his "predictions" which somehow always seem to exceed the actual current box office projections/numbers. In other words, his predictions are always rising, so that they can always be above the current projections/numbers, and also so he can have bate in putting down the box office numbers of MOS.
To get rid of him however, all you have to do is quote one of his earlier lower predictions, when he posts his current higher predictions. This is a perfect example in this case (Props to Migu-EL on this one);
Notice that we have not heard from him since? Lol...
Don't forget, Tobias is a massive Superman Fan, so as he always mentions, do not forget to read his fan stories at www.fanfiction.net/
