Main jungle and always get abuse

Ok so i only really play jungle, i enjoy it and think i am quite good at it however about 50% of games i get abused for everyone else's problems. Some games we win i get flamed, and most games i loose i get flamed. I main udyr, i always do well, if my team feeds or over extends without wards, i am the one blamed, "omg jungler where are you?"

So with udyr you need to farm a lot, i will gank when i can but there is no point wasting time. I often gank lanes get them the first blood or kill or whatever. To then see them die 3 times after, they then blame me "omg udyr gank me!" i cant babysit every lane and if all lanes are moaning and crying then i just mute my team and gank when it suits me. I played a game and my team where so negative, they flamed me for everything. Come to their lane, get them a kill, then push the wave out to turret so we can back. They ping and flame and rage that i took like 3 cs, despite getting them a kill they say they will report. They then try and steal your jungle, i had such a toxic team that where all ganging up on me because i was split pushing when they decided they wanted to fight. I said "dont fight" and they all die, i get an inhib turret and they flame me so much, so i mute them. I pushed out lanes, while they constantly looked for fights to have. Soon i was full build before anyone else, we where losing a lot and then i joined a team fight when we had good push, and i got a quadra kill, my team got away with so little health and we all lived, whilst they went back i got an inhibitor turret and inhib, with my elixir i bought and just managed to run away from their respawn, i was pretty happy with this play, i felt like i turned the game for us. So i un-mute my team thinking they wouldnt be so toxic....

Vayne and janna are going "report udyr for KS, udyr noob let the adc have the kills" when vayne was so nearly dead that she wasn't even fighting at the end of the team fight.... now this is the worse that it has been, however 50% of my games i get flamed for doing anything. People instablame the jungler. I now often just mute my team at the start and do my own thing.
