Calling preflop raises after limping" Revisited

[AmericanAirlines]

Hi Everyone,
Back around September there was a thread called:

Calling preflop raises after limping: How to exploit & avoid

The initial post I've quoted below. Seems general concensus was that the second call gets even better pot odds than the first, so you should always call the second time around.

So I'm sure I must've missed something...

What would you fold in this position? My guess is anything that depends on implied odds for it's +EV since you are paying more upfront, thus wrecking the ration of upfront cost to back end bets.

Sincerely,
AA

"In LL games I regularly see that 5 players will limp in, get raised by an LP, and then all of the players will call. It looks something like this: limp, limp, limp, limp, limp, raise, call, call, call, call, call.

Two questions:

1. How do I exploit this? One idea is to raise for value in LP with drawing hands (e.g., 77, QJs).

2. How do I avoid this problem? Which hands should I fold to a preflop raiser after limping in?"
