Need advice

So my guild has an officer dating a raider who’s trialing as the raid lead next reset and I’m also an officer and I’ve received a few complaints regarding the raider/trial raid lead’s comments and actions from a few members being either elitist, snide or just being an ass. I haven’t noticed anything personally but I haven’t been paying much attention to comms as a whole and I’m more just concerned if I need to worry if favoritism and nepotism will become a future problem. I wanna give them the benefit of the doubt but at the same time I wanna stop any possible toxicity or problems before they grow as my guild rebuilds for dragonflight. Thanks in advance for any feedback or advice.
