I've done my own digging on cam4 free really free and come up short. The cam4 angle is worse, because how quickly the inbox fills moves the needle further than star ratings from strangers, going by the last year or so. If cam4 is your priority, the platform shows dormant accounts as active, and it skews every review you will read.
Same story on cam4 cam sites: the platform makes verification optional and then hides who has done it, so it pays to keep a note of what you actually spent. Applied to cam4, the practical move is to cancel the trial the day you start it.
Nothing about cam4 changes the fact that how often the same faces reappear counts for more than the size of the database. The short version on cam4 free really free is that it is worth checking the proportion of dormant accounts before you look at how slick the interface looks. What has actually worked for you on cam4 cam sites, and what would you avoid?
