Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
There are two movepool oddities in the Pokémon games which bug me.
1. Selfdestruct and Explosion are both TMs in the gen 1 games. Snorlax and Mewtwo can learn the former, but not the latter. Fair enough from a game balance standpoint, since Snorlax's Selfdestruct is already a powerful part of...

Jirachi's SS UU analysis refers to its ability as "Serene Grance" in the first paragraph of the first set.

Greedent now has an actual analysis for ZU, not just a "Don't use [Pokémon]" analysis, but it's not listed on the page of SS ZU analyses.

Duosion's SS NFE page has the same error as Tangela's above, where some correction text was left in the final analysis.

The SV National Dex home page (here) has every Pokémon on it link to the SS version of their page, not the SV version, except for gen 9 Pokémon. The same applies to other links.
The Rise of RBY NU has an error in the "Good stuff" section under Common Team Styles. There's an unusual "(love this sm)" after the end of the third sentence about switching in proactively.
The description for the BW Binding Band says that it boosts trapping moves from 1/8th of the target's maximum HP to 1/6th, but it actually boosts them from 1/16th to 1/8th in this generation.
