He will carry on as usual. I don't think he is going to slow down on the channel as he threatened. It would be an admission of defeat.
All of his threats to this end are pathetic attempts to manipulate his donor base and to try to attract new ones. The problem for him is that there are still roughly 10-20 drops at the end of the month. As he approaches his new lows, these have shrunk to slightly more than 10. This wasn't a problem for him before as he had 30-40 sign up during a given month. Last month he actually had a negative drop during the month which is a large reason why he had no buffer to prevent him from sinking below 400 again.
His business model is at a crossroads. The monthly drops were typical even when he had over 800 patrons. These were from people who dropped due to losing interest, leaving the community, not seeing the need to donate or simply not being able to afford it. So, he has to gain at least 10 during the month to stay even, and 20 -30 gains per month to see any real growth as he outlined in his request to get back to 620, even 500 patrons.
The trend is still slightly downward and he's tried everything for the past 13 months to get it to reverse. This could mean another series of begging/threats to leave, or as I think more likely, he'll be working behind the scenes and letting people know he's hurting. He's gained 4 back so it might be due to private lobbying. I imagine he'll try to keep Tibor and Ramacro as long as he can, since dumping them will create the illusion he's about to fold.
Still, he's lost the entire bump he has received as a result of his begging tweets. He can't keep on running back to this every few months and not have the more rational patrons of his think they are giving money to a sinking ship. 500 and especially 620 patrons are unrealistic goals of his as it sits. Begging failed. He'll try something else not as blatant.
