Removing the top10 list might indeed take care of the problem more effectively than any other measure.
Half of the top10 series are also in most users list. Naruto would make sixth if the tempvotes were permanent.
Of the four other in most users list, Eva's vote distribution follows the fanboy-curve (just not strong enough to make to top10 - at 8.53 it falls 0.08 short of the top10), but in that case I do even agree that it's quite controversial and thus both 1 and 10 could be justified.
With Samurai Champloo it's too early to say whether it's in top10 to stay - it doesn't have the fanboy vote distribution, but it's so new series that it hasn't even been able to start in the voting wars yet

I haven't seen it yet, so don't know about how fanboyish it was.
Kumo no Mukou has a nice fanboy voting graph, but it didn't feel like one to attract a fanboy crowd. With the low number of votes as of yet it would easily fall victim to even a small hate-attack, dropping from the list with just seven 1's (assuming temporary votes become permanent as they are now). However, at it's current position it shouldn't need to worry about attacks much - it's far enough from the battlefield still. Entering the battlefield in it's current low votecount might be fatal though.
Juuni Kokki has strong enough votecount that it's not as easy a target as Kumo no Mukou. It's vote graph is a little more balanced than eg. Kenshin OVAs (which doesn't really take much), and it has lots of temporary votes still waiting - votes distributed far from the fanboy curve. I'm guessing it's in top10 pretty much to stay, always below the fanboy-battles, so somewhere in the positions 4-7.
GTO, placed fourth, seems quite strong title in top10 as it's there despite the clear lack of large fanboy crowd (only 20% more 10s than 9s).
Kenshin OVA has a very strong fanboy vote distribution and thus may seem a little weak - until you notice the number of votes. Even without troops rallying to support it's position with a few extra 10s it could endure a fairly strong hate attack and still stay on the list.
FMA (current leader) seems strong top10-title. It has pretty much everything: strong, large votecount, fanboy crowd, and ARC awards to attract people even if it wasn't the top10 leader.
Now, if we just had to surrender two places in the top10 list to fanboy battle it wouldn't be that big a problem. But, what happens when new fanboy-powered contenders arrive? Old titles are NOT going away, they have high votecounts and average ratings, so they will stay on the list pretty much forever.
