Unfortunately, that doesn't seem to be the case.
I've been gathering all sorts of possible data that I can regarding draws from the last year, and here's the graph for the average number of new candidates in the 450-1200 range, per day, in the last draws.
On draw 116, the one before FST draw in May 2019, the number of candidates added between draw 115 and 116 was 247 candidates/day.
The draw after the FST #117, had a 281 candidates/day average (again, this is for the 450-1200 range, I'm not considering the total amount of candidates in the pool).
Finally, this week's, March 4th, draw 138 had a 266 candidates/day average.
To sum it up: The average hasn't really changed THAT much since last year. Yes, it's trending upwards, but not drastically. What that means? That it's not a matter of a plethora of fake profiles entering the pool, but actually the quality of these profiles. If you imply that, let's say, half of the new profiles entering the pool are fakes, than you also need to imply that was the case in June 2019 as well, because the average candidates/day hasn't changed considerably.
NOTE: the spike in the graph happened in the B2B draw in December. Even though only 5 days passed between the 2 reference days*, the number of people in the pool remained close to the same amount, which indicates the influx of candidates between Dec 11th and Dec 16th was massive, for some mysterious reason (that's actually the only case where we could investigate a possible fraud regarding automatic profile creation)
* The graph was plotted based on the reference date for the breakdown of points published in every draw, instead of the actual date of the draws.
