For example, if you see someone struggling badly, it virtually NEVER happens that people offer to swap lanes, lend support, or generally help them out. Most of the time it's "OMG noob feeder" from the rest of the time.
Clearly, sometimes they are just beyond help, but helping people get better IS actually a positive.
Mind you, LoL has probably the most horrific, toxic community i;ve ever seen in general, especially in pub games, so nbs.
Btw, not suggesting you could have helped them in this case...if they blamed the jungler, they probably were WAY past help! Just something I have noticed in general.
