Casino Your Input Please Max-bet restriction on free-spin winnings (MG)

Some of you know that some MG casinos offer free spins for certain deposit-amounts. I took benefit of an offer from a Vegas Partner Lounge casino:
Deposit €100, get 65 free spins for Immortal Romance.

I played the free spins after my deposit and won €3.65. So my total balance was €103.65.

According to their T&C:
Quote:
5.6.3 All play will be reviewed for irregular playing patterns before any cashins will be processed. As per the Casino's policy on fair gaming, irregular game play includes:
(...)
- placing single bets equal to, or in excess of 30% or more of the value of the Bonus credited until the wagering requirements for that Bonus have been met
So am I right that I was restricted to placing wagers up to €1.09 after I've played the free-spins? Do I really have to fear to have my winnings void if I continue playing IR with €1.20 bets? That would be a big disadvantage of these offers because if you win plenty on those free-spins you have huge WR, if you win close to zilch you will be restricted severely on your bet-size.

VPL is not the only group that has this rule in their T&C. Fortune Lounge has set max-bet to 15% of the bonus, so even more problematic. At GoWild/WJ it's 20% but you can always place wagers up to €10, so that wouldn't be a problem there.

I'm interested to hear your thoughts on this.
