Don't let them farm at all. Keep the lane frozen, and poke the hell out of them if they try to farm. Even better if you have a good engage or poke support to zone them off farm.
Bruisers bot are shitty troll picks, stop doing it.
Say I pick Ashe, Cait, or Jinx, long range and decent disengage. What do I do about Alistair, Kayn, Leona, Naut, Thresh, Blitz, and any other support who wants you to be aggressive so they can engage? It isn't possible to just harass them for free because it ours you closer to the enemy and they will just hard engage on you.
Sure, say i play 
and do that, but then they can just call the jungler down and dive turret, or hard engage after putting any damage on my ADC, since I can't outsustain or outdamage that in early levels.
Or even if that works, and I get a huge 1-2k gold lead, at 5k I'm sitting on 
And they're still buying a completed item or that and 
, and with that plus ults up we don't win that lane anymore.
