raise MAX_DISTINCT_TO

Hello, i'm trying a strategy that requires me to interact with more than 2 addresses. Some time it's up to 5. Right now it's not possible to me to use such strategy.

Is there a reason why this param was introduced? Or is it just because of spam?

Start by locating MAX_DISTINCT_TO and reading the surrounding code to determine why the limit exists and whether it is intended to prevent spam. Check how distinct addresses are validated and whether any tests cover the current limit. Done means establishing a safe supported limit for strategies using more than two addresses and documenting or testing the resulting behavior.
