Abstract
In this paper, we show that a possible version of the swampland weak gravity conjecture for higher spin (HS) massive topological AdS$_{3}$ gravity can be expressed in terms of mass $M_{hs}$, charge $Q_{hs}$ and coupling constant $g_{hs}$ of 3D gravity coupled to higher spin fields as $M_{hs} \leq \sqrt{2}$ $Q_{hs}$ $g_{hs}$ $M_{Pl}$. The higher spin charge is given by the $SO(1,2)$ quadratic Casimir $Q_{hs}^{2}=s\left (s-1\right) $ and the HS coupling constant by ${\large g}_{hs} ^{2}=2/\left (M_{Pl}^{2} l_{AdS_{3}}^{2}\right )$ while the mass expressed like $\left( l_{AdS_{3}} \text{M}_{hs}\right) ^{2}$ is defined as $ \left (1+\mu l_{AdS_{3}} \right ) ^{2} s \left ( s-1 \right ) +[1- \left ( \mu l_{AdS_{3}} \right ) ^{2} \left ( s-1 \right ) ]$.

Report
In the revised version, the authors have enhanced their discussion in section 4.1 by providing a better justification for their identification of $j(j+1)$ with $s(s-1)$. They accomplish this through a comparison between the charge term in super-extremality conditions for particle states in D-dimensional effective theories coupled to gravity and the notion of higher spin charge relevant to their case. The authors now also elaborate on how, in the Kerr-Newman scenario, one can go from bounds on particle states to bounds on black holes, while explaining why they believe a similar derivation in their context is too challenging to include in the present work and needs to be deferred to future research.
I believe the authors have now more effectively addressed the remaining issue with the manuscript, highlighting the limitations of their current analysis. I would encourage them to emphasize these points in their conclusions as well, reiterating the need for future work to fully address this matter. With these considerations in mind, I am happy to recommend this work for publication.
