I addressed that thanks to gratefuldisc. However, having an improperly sealed fermenter isn't a good thing either..
I'm only gonna address this one, since some of your tone is downright rude...I wasn't rude in my post, I simply said I didn't buy your argument. And have had differnet experiences in a lot of batches, as have many many others on here.
We say here all the time, if co2 is getting out someplace, 02 is not getting in. It's that simple.
There is STILL no need to worry if an airlock isn't bubbling.
Many people simply put lexan sheets on top of buckets instead of lids and airlocks, letting the co2 get out in the gap between the top and the bucket lip. Others leave their bucket lids on losely. Many on here use tinfoil on their carboys instaid of a bug.
Midwest supplies just released a vent stopper making an airlock totally obsolete.
The things that could possibly get into a fermenter and cause problems are not ninja accrobats. If Co2 is getting out...then those things can't get in.
We, on here have been answering this very question on here 5-10 times a day
for years. and contrary to what you may be convinced, there haven't been a rash of bad fermentations or infections because an airlock isn't blipping.
In fact 99.5% if the time, then OP has come back and said, either their gravity was fine, and the beer was fermenting along happily, and they worried for nothing, or their beer turned out fine, with no infection or issues. And they thanked us for THIS advice.
We wouldn't be giving this advice, if we didn't trust it. And if we hadn't faced this same issue, thousands, if not 10s of thousands of times on here.
I didn't get this postcount playing stupid word games, I got it from helping people and giving them the same advice day in and day out...AND getting feedback day in and day out....If something comes up wrong, or incorrect then it doesn't get given. Snce I get the feedback from all the threads I post in (I subsribe to all my threads), I SEE what the results of my advice...
You may not agree with it...But I stand by it. It's worked for other brewers on here, long before you came upon it....
