Probably attrition. Casual users of the forum aren't that engaged, so if you make life harder for them they just lose the habit of visiting. The forum goes down for an unreasonably long maintenance, you add overly intrusive ads, you announce something like 2FA that no one wants and leave it up in the air for weeks, you fuck up the layout and leave it like that for a month, etc, these are all actions (or rather inaction) that lead to loss of users on long run.
