Greasy Fork

The new version may cause some misjudgments (in the Traditional Chinese interface).
The first one is a regular post, and the second one is an advertisement.

Firefox 132.0 + Tampermonkey 5.3.1

Try this:
1) Edit the script's code.
2) Go to line 4799.
3) Change the value 309 to 310.
4) Save and test the script.

5) If some ordinary posts are still flagged as sponsored, increase the 309 value by 1, until the false flagging stops.

Let me know if you find the "magic number" that works best for you.

After testing, it appears that the number 311 is the least likely to cause misjudgments in my case.

Thanks. Published v5.02 with fixes to the sponsored posts detection code.
