So Blaze trader, they also set targets ahead of time, and you can follow each and every trade? It doesn't take much playing around to turn losing trades into ingenious trades.
I can also vouch for LiveTraders as far as apparent transparency/authenticity. As Blaze said, they post entries and stops ahead of time. If they don't have time to post it, then they don't include the trade in their official results. Sometimes they even miss trades themselves because taking the time to post them interferes with their own order execution.
They often post targets early on, or will mention them verbally on the mic -- but they'll definitely tell you what they're looking for as targets if you ask. They each manage their trades slightly differently, so their targets aren't always set in stone from the beginning, even if they have a general target(s) in mind... but they'll also usually give a heads up prior to taking some off. They provide detailed analyses of their trades, and will admit to mistakes, mismanaging trades or getting shaken out when it happens.
As far as fudging results -- they post some fairly significant losers/losing days (and losing streaks), as well as mediocre days, so not sure what their incentive to do so would be if they wanted to embellish their results. They also provide screen shots of their PnL (one shares his TS platform live). Posted trades are listed under a separate chat tab, and official results are provided EOD (or by no later than the next day), and summarized at the EOM, so you can also compare those vs. their posted trades. If you look at their stats (e.g., batting average, "Sharpe"), they're not exceptional as far as being "unbelievable"/incredible... but consistently very profitable over the long run. While that's not *proof* of real trading, it's what you might expect from real (professional, successful) traders.
In general -- they seem to try really hard to post timely, actionable trades, and be fully transparent about their results, which they promote as one of their service's core values.
