BTC.top is mining blocks at a loss when BCH mining is not profitable and the block interval exceeds 1 hour -- thank you!

Between Feb 1st and Feb 23rd, it had taken at least 1 hour between blocks 59 different times. Of the 59 blocks that broke these dry spells, 37 were mined by BTC.top, or 62.7%. The hashrate during these dry spells is otherwise about 2.0-2.5 EH/s, which indicates that BTC.top is moving about 4 EH/s over to BCH during long dry spells -- that's about 100% of their SHA256 hashrate.

This behavior started on Feb 1st. There were 175 blocks that took at least 1 hour to mine between Dec 15 and Jan 31st, and of those, only 6 (3.4%) were mined by BTC.top. Before Feb 1st, BTC.top was actively avoiding unprofitable mining. Now, they're actively seeking it out during the worst dry spells with the intent to prevent confirmation times from getting too long.

During dry spells, it's usually around 10% more profitable to mine BTC than to mine BCH, so each time BTC.top does this, they're losing around $440 in revenue. That's about $16,400 so far, or around $20,000 per month.

I think BTC.top deserves a big thank you for doing this.

I also think the BCH community needs to fix the difficulty adjustment algorithm, since that's the reason why we're getting these dry spells in the first place. Teaser: i'm working on a video and/or article explaining the problem and how we can fix it. This discovery came while doing research for that. Expect it to be published within the next few days.

Below is a list of all blocks since 613500 that took more than 1 hour to mine (according to their timestamps), what the exact delay was (in seconds), and whether they were mined by BTC.top, if anyone is curious. I also have data on who mined the rest, but I omitted it from this list to make it easier to read. (BTC.com and BTC.top were too hard to visually distinguish from each other.) If anyone wants the full list, let me know and I'll reformat it and post it in a comment.
