This is an unfair, sweeping generalisation, but the risk of toxic players is something that LFG will always have. If I see a post asking for an unreasonable number of clears, especially so soon after release, it's not worth looking into. Some people ask for absurdly high power levels, without even knowing how it works - I saw multiple people asking for 1320+ on Day 1, even though the Contest power cap was 1300. When making posts, I always make it clear that beginners are welcome - by definition, all the toxic people were inexperienced and hadn't cleared the Raid at one point in time. It's a much nicer experience, anyway. If you offer to teach people, you are guaranteed to have a team that goes with whatever strategy you know works, instead of clashing with people who insist that their way is better. Plus, they really get into it! At the end of a Raid, it's way better to hear people talk about how much fun they had and thanking you for the help than it is to see them leave without saying a word.
