The tactical downvote protection seems weak at best.
To put myself in the position of such a person who would tacticaly downvote, if only one out of 10 tactical downvotes earns me an upvote then it's worth it. This is bevausebecause a downvote costs me 1 but an upvote gets me 10. If tactical downvoting doesn't achieve even this then I'm not sure why people are even bothering.
As such I would support removing this restriction for both up and downvotes.
