a lot of people (~ 7/10) are fast with words, saying "yes ofc i donate!!!111 / send beer money!!!11" and don't do a thing once they got what they want. The past has told.
I actually don't know if/how much i would donate, it would be up to some factors.
for example, how profitable this is. assuming it changes nothing compared to gb2 (just a thinking-comparison, not a fact one) i don't see much sense in donating. If it gathers for example at 50% of the speed, but lasts twice as long until banned, nothing is won on my side. on the other hand, if it gathers at 200% and lasts twice as long, i'll be make some decent profit and don't mind to share some with the creator of the tool i use.
Never the less i appreciate your work, but without profit, theres no money for donating.
Reason #1 i don't donate to CCs but invest some time to write my own or use modified free ones.
vote #3, obvious.
