calculate the block until timestamp with exponential backoff
if a filler faded multiple times in between the last post timestamp and now,
we apply a 1.5 multiplier for each fade
we apply a 1.2 multiplier for each fade

examples:
- 1 fade, 0 consecutive blocks: 15 minutes
- 1 fade, 1 consecutive blocks: (1.5 ^ 0) * 15 * 2^1 = 30 minutes
- 1 fade, 2 consecutive blocks: (1.5 ^ 0) * 15 * 2^2 = 60 minutes
- 1 fade, 3 consecutive blocks: (1.5 ^ 0) * 15 * 2^3 = 120 minutes
- 2 fades, 0 consecutive blocks: (1.5 ^ 1) * 15 * 2^0 = 22 minutes
- 2 fades 1 consecutive blocks: (1.5 ^ 1) * 15 * 2^1 = 45 minutes
- 2 fades 2 consecutive blocks: (1.5 ^ 1) * 15 * 2^2 = 90 minute
- 3 fades 0 consecutive blocks: (1.5 ^ 2) * 15 * 2^0 = 33 minutes
- 3 fades 1 consecutive blocks: (1.5 ^ 2) * 15 * 2^1 = 67 minutes
- 3 fades 2 consecutive blocks: (1.5 ^ 2) * 15 * 2^2 = 135 minutes
