I've tweaked that first suggestion and suggested it to Ryan as follows: "Repair scrolls that can be obtainable by voting and would repair a broken item." These could be scabale with donator rank and essentially the same as blood lust scrolls. As a sponsor you could vote on four sites and claim 4 vote points, 20 blood lust scrolls, and now 20 repair scrolls.
For the second suggestion I think a universal drop rate bonus for the day is too OP. You can vote every 12 hours so essentially you'd have an infinite 5% drop rate bonus just by voting. I believe a better alternative would be grant a 5% drop rate bonus for one hour per 4 sites voted on so (15 minutes per site).
