STAR? Sure.
Approval? Nah
Gonna copy paste my comment again:
I can see a bit of strategic voting happening.
Let me demonstrate:
For the sake of simplicity, let’s say we have 3 candidates, and no term limits:
Trump, Biden, Sanders
Biden and Sander voters dispise trump, their preference in RCV is (example):
Biden>Sanders>Trump: 30%
Sander>Biden>Trump: 25%
Trump>Sanders>Biden: 23%
Trump>Biden>Sanders: 22%
Okay, so lets say they all approve their top 2:
Biden: 77%
Sanders: 78%
Trump: 45%
Okay we have president Sanders! Congrats, right?
Well, now the trumpers who approved sanders are like: “Hey wait a minute, we made our daddy lose because we approved Sanders”
All the trumpers now have a meeting and decided that next election, they don’t approve Sanders or Biden as a strategic vote.
So now, Election 2 Results:
Biden: 55%
Sanders: 55%
Trump: 45%
Oh great, it’s a tie. The law says that the election have to be re-done to solve the tie:
Now this next election, all people who preferred Sanders first go to a Sanders supporter meeting and started saying: “Lets disapprove Biden so Bernie can win!”
Simultaneously, Biden voters will be like: “Lets disapprove Sanders so Biden can win!”
Next election results:
Trump: 45%
Biden: 30%
Sanders 25%
Congrats, we have a glorified FPTP and spoiler effect yet again!
Now, other election systems could also have strategic voting, but its less likely with, for example, RCV, since you can rank candidates.
STAR voting is also acceptable, but its also less heard of, and as far as I know, it hasn’t ever been done in a real-life election. I doubt that’ll get popular any time soon, might as well find another easier to implement Non-FPTP system to rally behind.

Not quite. As you’ve just observed, this kind of strategic voting is risky, and self destructive. Which means that many would recognize this, and not use this voting strategy. Its a game of chicken, and lots of people prefer not to play such a game and instead support the safe bet, which means supporting those you genuinely support.
And as !ammonium@lemmy.world pointed out, it isn’t possible to have a perfect voting system.
Then there is the fact that there is more to this than just voting strategies. There are the other effects to keep in mind. For example approval is far simpler to explain than RCV, especially when you explain how the counting works.
Another example is that approval is purely an additive process for counting, RCV is not. That means auditing results is significantly easier and quicker under approval than RCV. That leads to higher voter confidence in results than RCV audits.
RCV still can experience the spoiler effect just as FPTP, because it is in effect FPTP taking place over some number of instant rounds.
