I disagree, I think in HTH you potentially have less risk streaming. A team can quickly decide if they want to stream that week or not depending on who you're facing (if they have a great staff), how the matchups stack-up (their top3-4 pitchers all pitch twice against the Astros and at Petco that wee), or how the starts go in the first 2-3 days. If they get behind, are facing a top staff, or have bad matchups they can stream freely knowing that they probably lose those pitching stats for the week if they don't and that if ERAs blow up it just resets the very next week. There's no long-term ratio penalty for having a crappy stream guy give up 6 ER in 0.2 IP.
So I think if you want to avoid streaming you have to make more of an effort. Like the others I think limiting moves/starts/max innings on a weekly basis is the way to go. Maybe 3-4 moves a week max or 10 starts a week max or 60 IP max per week. One other way to curtail streaming is to go to a 6x6 league (using OPS, fielding%, CS for the offense) and use a negative pitching stat like L or HR allowed. This adds an extra stat category that you'll likely lose if you stream.
I'd also advise that you put in a minimum number of IP or starts. Otherwise you'll have a guy draft offense for the first 9 rounds, punt W and K and try to take ERA/WHIP/SVs with a staff full of relievers.
