How much did you pay? Less than the usual $250? Haven't seen a discount for lifetime on VR Bangers in the last months.
And why did you think there are more releases than once per week? Do they advertise that? Most studios (including VR Bangers) show release dates on their website for each scene, so it's quite easy to check how many videos they release per month.
If a studio doesn't show release dates or doesn't offer an option to sort by release date, they usually want to hide something. Some studios like XsinsVR fake release dates by releasing old videos with a new date - but that's not common.
