Adding friends to group limit: no more than 600 in 24 hours. Mass follow limit: the account gets banned after 400-450 follows in 24 hours, and it will require providing an ID to unblock it.This means, limits and bans differ for pages, groups, and individuals. Otherwise, one of them is just a follower of another. People are considered to be friends only if both of them have consented to. You should keep in mind, there’s a strict Facebook policy towards friends relationship.

Thus, a first-principles calculation uncovered hitherto hidden patterns underlying the highly noisy checkpoint override process. Based on these two measurements, the optimal checkpoint theory predicted remarkably accurately the DNA damage checkpoint override times as a function of DSB numbers, which we also measured for the first time precisely. Using a novel fluorescent construct which allowed cells with DNA breaks to be isolated by flow cytometry, we quantified i) the probability distribution of repair for a double-strand DNA break (DSB), including for the critically important, rare events deep in the tail of the distribution and ii) the survival probability after override. We applied the theory experimentally to the DNA damage checkpoint in budding yeast, an intensively researched model for eukaryotic checkpoints, whose override is nevertheless not understood quantitatively, functionally, or at the system level. The theory predicts the optimal override time without free parameters based on the statistics i) of error correction and ii) of survival. We show that the mathematical problem of finding the optimal strategy maps onto the question of calculating the optimal absorbing boundary for a random walk, which we show can be solved efficiently recursively. To uncover laws governing the dynamics of error-correction systems, we derived a general theory of optimal checkpoint strategies, balancing the trade-off between risk and self-replication opportunity. Although critical for the organism, checkpoint override is not understood quantitatively by experiment or theory. Specifically, checkpoints in yeast and animals are overridden after prolonged arrests allowing self-replication to proceed despite the continued presence of errors. Why biological quality-control systems fail is often mysterious.
