Let $Δ$ be an (abstract) simplicial complex on $n$ vertices. One can define the Artinian monomial algebra $A(Δ) = \Bbbk[x_1, \ldots, x_n]/ \langle x_1^2, \ldots, x_n^2, I_Δ \rangle$, where $\Bbbk$ is a field of characteristic $0$ and $I_Δ$ is the Stanley-Reisner ideal associated to $Δ$. In this paper, we aim to characterize the Weak Lefschetz Property (WLP) of $A(Δ)$ in terms of the simplicial complex $Δ$. We are able to completely analyze when WLP holds in degree $1$, complementing work by Migliore, Nagel and Schenck in [MNS2020]. We give a complete characterization of all $2$-dimensional pseudomanifolds $Δ$ such that $A(Δ)$ satisfies WLP. We also construct Artinian Gorenstein algebras that fail WLP by combining our results and the standard technique of Nagata idealization.
