So, if somebody vandalizes he gets a 3 years block. Do you think, that the same person will return after 3 years to vadalize again just to get another 3 years block, and after another 3 years (total 3+3) returns again and vandalize again to get a permanent block?
 * Vandalizing: Block for 3 years
 * Too much spamming/vandalism (3 times of more): permanent block.

Do you think that somebody is so much interested in vandalizing that wiki, that he will vandalize it for 6 years?

Will YOU be interested in the wiki so much, that you will be still an admin there even after those 6 years?
