I have had a few ask me how I managed this, and honestly it was mostly luck if anything I got 161 rewards from one task I normally get about 30 or so
To do it I have 6 characters loaded through innerspace , and a key broadcast so I set my key combination in IS to press 'h' for hailing.
Then I set up a G15 key to press said combination with a 0 or 1 ms delay, I find depending on my ping I get a more consistent response with 1ms vs 0ms
When ready to hail, press G key and hold until window pops up abs release. Once the window pops up normally that's it for any chance of extra rewards.
Beware, I hold no responsibility for anything that happens from the use of this. Use it carefully and if you manage to get 100+ rewards it normally lags A LOT and you will have to wait until the pop up window telling how many to claim before zoning stops counting. And claiming each reward until under 100 normally lags A second before claiming the next.
Have fun and be smart.
